Makefile.am: Since automake is smarter than I am and knows how I
should work, I made a script to generate a Makefile.am so that it
can't complain. Now runs through distcheck with no errors!

The language used in <span class="application">Genius Mathematics Tool</span> is designed to be + ‘mathematical’ in the sense that it should be ‘what + you mean is what you get’. Of course that is not an + entirely attainable goal. <span class="application">Genius Mathematics Tool</span> features rationals, arbitrary + precision integers and multiple precision floats using the GMP library. + It handles complex numbers using cartesian notation. It has good + vector and matrix manipulation and can handle basic linear algebra. + The programming language allows user defined functions, variables and + modification of parameters. + </p><p> + <span class="application">Genius Mathematics Tool</span> comes in two versions. One version is the graphical GNOME + version, which features an IDE style interface and the ability + to plot functions of one or two variables. + The command line version does not require GNOME, but of course + does not implement any feature that requires the graphical interface. + </p><p> + Parts of this manual describe the graphical version of the calculator, + but the language is of course the same. The command line only version + lacks the graphing capabilities and all other capabilities that require + the graphical user interface. + </p><p> + Generally, when some feature of the language (function, operator, etc...) + is new in some version past 1.0.5, it is mentioned, but + below 1.0.5 you would have to look at the NEWS file. + </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="ch02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Genius Manual </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 2.

For example, a number in base 23 could be written: +</p><pre class="programlisting">23\1234ABCD +</pre><p> + </p><p> +The second type of GEL number is rationals. Rationals are simply achieved by dividing two integers. So one could write: +</p><pre class="programlisting">3/4 +</pre><p> +to get three quarters. Rationals also accept mixed fraction notation. So in order to get one and three tenths you could write: +</p><pre class="programlisting">1 3/10 +</pre><p> + </p><p> +The next type of number is floating point. These are entered in a similar fashion to C notation. You can use <code class="literal">E</code>, <code class="literal">e</code> or <code class="literal">@</code> as the exponent delimiter. Note that using the exponent delimiter gives a float even if there is no decimal point in the number. Examples: +</p><pre class="programlisting">1.315 +7.887e77 +7.887e-77 +.3 +0.3 +77e5 +</pre><p> + When Genius prints a floating point number it will always append a + <code class="computeroutput">.0</code> even if the number is whole. This is to indicate that + floating point numbers are taken as imprecise quantities. When a number is written in the + scientific notation, it is always a floating point number and thus Genius does not + print the <code class="computeroutput">.0</code>. + </p><p> +The final type of number in GEL is the complex numbers. You can enter a complex number as a sum of real and imaginary parts. To add an imaginary part, append an <code class="literal">i</code>. Here are examples of entering complex numbers: +</p><pre class="programlisting">1+2i +8.01i +77*e^(1.3i) +</pre><p> + </p><div class="important" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Important</h3><p> +When entering imaginary numbers, a number must be in front of the <code class="literal">i</code>. If you use <code class="literal">i</code> by itself, Genius will interpret this as referring to the variable <code class="varname">i</code>. If you need to refer to <code class="literal">i</code> by itself, use <code class="literal">1i</code> instead. + </p><p> +In order to use mixed fraction notation with imaginary numbers you must have the mixed fraction in parentheses. (i.e., <strong class="userinput"><code>(1 2/5)i</code></strong>) + </p></div></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a name="genius-gel-values-booleans"></a>Booleans</h3></div></div></div><p> +Genius also supports native Boolean values. The two Boolean constants are +defined as <code class="constant">true</code> and <code class="constant">false</code>; these +identifiers can be used like any other variable. You can also use the +identifiers <code class="constant">True</code>, <code class="constant">TRUE</code>, +<code class="constant">False</code> and <code class="constant">FALSE</code> as aliases for the +above. + </p><p> +At any place where a Boolean expression is expected, you can use a Boolean +value or any expression that produces either a number or a Boolean. If +Genius needs to evaluate a number as a Boolean it will interpret +0 as <code class="constant">false</code> and any other number as +<code class="constant">true</code>. + </p><p> +In addition, you can do arithmetic with Boolean values. For example: +</p><pre class="programlisting">( (1 + true) - false ) * true +</pre><p> +is the same as: +</p><pre class="programlisting">( (true or true) or not false ) and true +</pre><p> +Only addition, subtraction and multiplication are supported. If you mix numbers with Booleans in an expression then the numbers are converted to Booleans as described above. This means that, for example: +</p><pre class="programlisting">1 == true +</pre><p> +always evaluates to <code class="constant">true</code> since 1 will be converted to <code class="constant">true</code> before being compared to <code class="constant">true</code>. + </p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a name="genius-gel-values-strings"></a>Strings</h3></div></div></div><p> +Like numbers and Booleans, strings in GEL can be stored as values inside variables and passed to functions. You can also concatenate a string with another value using the plus operator. For example: +</p><pre class="programlisting">a=2+3;"The result is: "+a +</pre><p> +will create the string: +</p><pre class="programlisting">The result is: 5 +</pre><p> +You can also use C-like escape sequences such as <code class="literal">\n</code>,<code class="literal">\t</code>,<code class="literal">\b</code>,<code class="literal">\a</code> and <code class="literal">\r</code>. To get a <code class="literal">\</code> or <code class="literal">"</code> into the string you can quote it with a <code class="literal">\</code>. For example: +</p><pre class="programlisting">"Slash: \\ Quotes: \" Tabs: \t1\t2\t3" +</pre><p> +will make a string: +</p><pre class="programlisting">Slash: \ Quotes: " Tabs: 1 2 3 +</pre><p> +Do note however that when a string is returned from a function, escapes are +quoted, so that the output can be used as input. If you wish to print the +string as it is (without escapes), use the +<a class="link" href="ch11s02.html#gel-function-print"><code class="function">print</code></a> +or +<a class="link" href="ch11s02.html#gel-function-printn"><code class="function">printn</code></a> functions. + </p><p> + In addition, you can use the library function <a class="link" href="ch11s02.html#gel-function-string"><code class="function">string</code></a> to convert anything to a string. For example: +</p><pre class="programlisting">string(22) +</pre><p> +will return +</p><pre class="programlisting">"22" +</pre><p> +Strings can also be compared with <code class="literal">==</code> (equal), <code class="literal">!=</code> (not equal) and <code class="literal"><=></code> (comparison) operators + </p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a name="genius-gel-values-null"></a>Null</h3></div></div></div><p> +There is a special value called +<code class="constant">null</code>. No operations can be performed on +it, and nothing is printed when it is returned. Therefore, +<code class="constant">null</code> is useful when you do not want output from an +expression. The value <code class="constant">null</code> can be obtained as an expression when you +type <code class="literal">.</code>, the constant <code class="constant">null</code> or nothing. +By nothing we mean that if you end an expression with +a separator <code class="literal">;</code>, it is equivalent to ending it with a +separator followed by a <code class="constant">null</code>. + </p><p> +Example: +</p><pre class="programlisting">x=5;. +x=5; +</pre><p> + </p><p> +Some functions return <code class="constant">null</code> when no value can be returned +or an error happened.

Example: +<strong class="userinput"><code>2^(5!) * 3^(6!) mod 5</code></strong> +It could be possible to do modular arithmetic by computing with integers and then modding in the end with +the <code class="literal">%</code> operator, which simply gives the remainder, but +that may be time consuming if not impossible when working with larger numbers. +For example, <strong class="userinput"><code>10^(10^10) % 6</code></strong> will simply not work (the exponent +will be too large), while +<strong class="userinput"><code>10^(10^10) mod 6</code></strong> is instantaneous. The first expression first tries to compute the integer +<strong class="userinput"><code>10^(10^10)</code></strong> and then find remainder after division by 6, while the second expression evaluates +everything modulo 6 to begin with. + </p><p> +You can calculate the inverses of numbers mod some integer by just using +rational numbers (of course the inverse has to exist). +Examples: +</p><pre class="programlisting">10^-1 mod 101 +1/10 mod 101</pre><p> +You can also do modular evaluation with matrices including taking inverses, +powers and dividing. +Example: +</p><pre class="programlisting">A = [1,2;3,4] +B = A^-1 mod 5 +A*B mod 5</pre><p> +This should yield the identity matrix as B will be the inverse of A mod 5. + </p><p> +Some functions such as +<a class="link" href="ch11s05.html#gel-function-sqrt"><code class="function">sqrt</code></a> or +<a class="link" href="ch11s05.html#gel-function-log"><code class="function">log</code></a> +work in a different way when in modulo mode. These will then work like their +discrete versions working within the ring of integers you selected. For +example: +</p><pre class="programlisting">genius> sqrt(4) mod 7 += +[2, 5] +genius> 2*2 mod 7 += 4</pre><p> + <code class="function">sqrt</code> will actually return all the possible square + roots. + </p><p> + Do not chain mod operators, simply place it at the end of the computation, all computations in the expression on the left + will be carried out in mod arithmetic. If you place a mod inside + a mod, you will get unexpected results. If you simply want to + mod a single number and control exactly when remainders are + taken, best to use the <code class="literal">%</code> operator. When you + need to chain several expressions in modular arithmetic with + different divisors, it may be best to just split up the expression into several and use + temporary variables to avoid a mod inside a mod. + </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch05s05.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch05.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch05s07.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Comments </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> List of GEL Operators</td></tr></table></div></body></html> diff --git a/help/C/ch05s07.html b/help/C/ch05s07.html new file mode 100644 index 00000000..9b752007 --- /dev/null +++ b/help/C/ch05s07.html @@ -0,0 +1,247 @@ +<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>List of GEL Operators</title><meta name="generator" content="DocBook XSL Stylesheets V1.79.1"><link rel="home" href="index.html" title="Genius Manual"><link rel="up" href="ch05.html" title="Chapter 5.

We will explain what this + means below. That is, normal variables and functions are dynamically + scoped. The exception are + <a class="link" href="ch06s06.html" title="Parameter variables">parameter variables</a>, + which are always global. + </p><p> + Like most programming languages, GEL has different types + of variables. Normally when a variable is defined in a function, + it is visible from that function and from all functions that are + called (all higher contexts). For example, suppose a function + <code class="function">f</code> defines a variable <code class="varname">a</code> + and then calls function <code class="function">g</code>. Then + function <code class="function">g</code> can reference + <code class="varname">a</code>. But once <code class="function">f</code> returns, + the variable <code class="varname">a</code> goes out of scope. + For example, the following code will print out 5. + The function <code class="function">g</code> cannot be called on the + top level (outside <code class="function">f</code> as <code class="varname">a</code> + will not be defined). +</p><pre class="programlisting">function f() = (a:=5; g()); +function g() = print(a); +f(); +</pre><p> + </p><p> + If you define a variable inside a function it will override + any variables defined in calling functions. For example, + we modify the above code and write: +</p><pre class="programlisting">function f() = (a:=5; g()); +function g() = print(a); +a:=10; +f(); +</pre><p> + This code will still print out 5. But if you call + <code class="function">g</code> outside of <code class="function">f</code> then + you will get a printout of 10. Note that + setting <code class="varname">a</code> + to 5 inside <code class="function">f</code> does not change + the value of <code class="varname">a</code> at the top (global) level, + so if you now check the value of <code class="varname">a</code> it will + still be 10. + </p><p> + Function arguments are exactly like variables defined inside + the function, except that they are initialized with the value + that was passed to the function. Other than this point, they are + treated just like all other variables defined inside the + function. + </p><p> + Functions are treated exactly like variables. Hence you can + locally redefine functions. Normally (on the top level) you + cannot redefine protected variables and functions. But locally + you can do this. Consider the following session: +</p><pre class="screen"><code class="prompt">genius> </code><strong class="userinput"><code>function f(x) = sin(x)^2</code></strong> += (`(x)=(sin(x)^2)) +<code class="prompt">genius> </code><strong class="userinput"><code>function f(x) = sin(x)^2</code></strong> += (`(x)=(sin(x)^2)) +<code class="prompt">genius> </code><strong class="userinput"><code>function g(x) = ((function sin(x)=x^10);f(x))</code></strong> += (`(x)=((sin:=(`(x)=(x^10)));f(x))) +<code class="prompt">genius> </code><strong class="userinput"><code>g(10)</code></strong> += 1e20 +</pre><p> + </p><p> + Functions and variables defined at the top level are + considered global. They are visible from anywhere. As we + said the following function <code class="function">f</code> + will not change the value of <code class="varname">a</code> to 5. +</p><pre class="programlisting">a=6; +function f() = (a:=5); +f(); +</pre><p> + Sometimes, however, it is necessary to set +a global variable from inside a function. When this behavior is needed, +use the +<a class="link" href="ch11s02.html#gel-function-set"><code class="function">set</code></a> function. Passing a string or a quoted identifier to +this function sets the variable globally (on the top level). +For example, to set +<code class="varname">a</code> to the value 3 you could call: +</p><pre class="programlisting">set(`a,3) +</pre><p> +or: +</p><pre class="programlisting">set("a",3) +</pre><p> + </p><p> + The <code class="function">set</code> function always sets the toplevel + global. There is no way to set a local variable in some function + from a subroutine. If this is required, must use passing by + reference. + </p><p> + See also the + <a class="link" href="ch11s02.html#gel-function-SetElement"><code class="function">SetElement</code></a> and + <a class="link" href="ch11s02.html#gel-function-SetVElement"><code class="function">SetVElement</code></a> functions. + </p><p> + So to recap in a more technical language: Genius operates with + different numbered contexts. The top level is the context 0 + (zero). Whenever a function is entered, the context is raised, + and when the function returns the context is lowered. A function + or a variable is always visible from all higher numbered contexts. + When a variable was defined in a lower numbered context, then + setting this variable has the effect of creating a new local + variable in the current context number and this variable + will now be visible from all higher numbered contexts. + </p><p> + There are also true local variables that are not seen from + anywhere but the current context. Also when returning functions + by value it may reference variables not visible from higher context + and this may be a problem.

This way you can + build functions that construct special purpose functions according + to some parameters. The tricky bit is what variables does the + function see. The way this works in GEL is that when a function + returns another function, all identifiers referenced in the + function body that went out of scope + are prepended a private dictionary of the returned + function. So the function will see all variables that were in + scope + when it was defined. For example, we define a function that + returns a function that adds 5 to its argument. +</p><pre class="programlisting">function f() = ( + k = 5; + `(x) = (x+k) +) +</pre><p> + Notice that the function adds <code class="varname">k</code> to + <code class="varname">x</code>. You could use this as follows. +</p><pre class="programlisting">g = f(); +g(5) +</pre><p> + And <strong class="userinput"><code>g(5)</code></strong> should return 10. + </p><p> + One thing to note is that the value of <code class="varname">k</code> + that is used is the one that's in effect when the + <code class="function">f</code> returns. For example: +</p><pre class="programlisting">function f() = ( + k := 5; + function r(x) = (x+k); + k := 10; + r +) +</pre><p> + will return a function that adds 10 to its argument rather than + 5. This is because the extra dictionary is created only when + the context + in which the function was defined ends, which is when the function + <code class="function">f</code> returns. This is consistent with how you + would expect the function <code class="function">r</code> to work inside + the function <code class="function">f</code> according to the rules of + scope of variables in GEL. Only those variables are added to the + extra dictionary that are in the context that just ended and + no longer exists. Variables + used in the function that are in still valid contexts will work + as usual, using the current value of the variable. + The only difference is with global variables and functions. + All identifiers that referenced global variables at time of + the function definition are not added to the private dictionary. + This is to avoid much unnecessary work when returning functions + and would rarely be a problem. For example, suppose that you + delete the "k=5" from the function <code class="function">f</code>, + and at the top level you define <code class="varname">k</code> to be + say 5. Then when you run <code class="function">f</code>, the function + <code class="function">r</code> will not put <code class="varname">k</code> into + the private dictionary because it was global (toplevel) + at the time of definition of <code class="function">r</code>. + </p><p> + Sometimes it is better to have more control over how variables + are copied into the private dictionary. Since version 1.0.7, + you can specify which + variables are copied into the private dictionary by putting + extra square brackets after the arguments with the list of + variables to be copied separated by commas. + If you do this, then variables are + copied into the private dictionary at time of the function + definition, and the private dictionary is not touched afterwards. + For example +</p><pre class="programlisting">function f() = ( + k := 5; + function r(x) [k] = (x+k); + k := 10; + r +) +</pre><p> + will return a function that when called will add 5 to its + argument. The local copy of <code class="varname">k</code> was created + when the function was defined. + </p><p> + When you want the function to not have any private dictionary + then put empty square brackets after the argument list. Then + no private dictionary will be created at all. Doing this is + good to increase efficiency when a private dictionary is not + needed or when you want the function to lookup all variables + as it sees them when called. For example suppose you want + the function returned from <code class="function">f</code> to see + the value of <code class="varname">k</code> from the toplevel despite + there being a local variable of the same name during definition. + So the code +</p><pre class="programlisting">function f() = ( + k := 5; + function r(x) [] = (x+k); + r +); +k := 10; +g = f(); +g(10) +</pre><p> + will return 20 and not 15, which would happen if + <code class="varname">k</code> with a value of 5 was added to the private + dictionary. + </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch07s02.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch07.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch07s04.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Toplevel Syntax </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> True Local Variables</td></tr></table></div></body></html> diff --git a/help/C/ch07s04.html b/help/C/ch07s04.html new file mode 100644 index 00000000..de8dff41 --- /dev/null +++ b/help/C/ch07s04.html @@ -0,0 +1,58 @@ +<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>True Local Variables</title><meta name="generator" content="DocBook XSL Stylesheets V1.79.1"><link rel="home" href="index.html" title="Genius Manual"><link rel="up" href="ch07.html" title="Chapter 7.

Since version 1.0.7 there are + true local variables. These are variables that are visible only + from the current context and not from any called functions. + We could define <code class="varname">k</code> as a local variable in the + function <code class="function">f</code>. To do this add a + <span class="command"><strong>local</strong></span> statement as the first statement in the + function (it must always be the first statement in the function). + You can also make any arguments be local variables as well. + That is, +</p><pre class="programlisting">function f(g,x) = ( + local g,x,k; + k := 5; + g(x) +); +</pre><p> + Then the code will work as expected and prints out 11. + Note that the <span class="command"><strong>local</strong></span> statement initializes + all the referenced variables (except for function arguments) to + a <code class="constant">null</code>. + </p><p> + If all variables are to be created as locals you can just pass an + asterisk instead of a list of variables. In this case the variables + will not be initialized until they are actually set of course. + So the following definition of <code class="function">f</code> + will also work: +</p><pre class="programlisting">function f(g,x) = ( + local *; + k := 5; + g(x) +); +</pre><p> + </p><p> + It is good practice that all functions that take other functions + as arguments use local variables. This way the passed function + does not see implementation details and get confused. + </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch07s03.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch07.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch07s05.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Returning Functions </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> GEL Startup Procedure</td></tr></table></div></body></html> diff --git a/help/C/ch07s05.html b/help/C/ch07s05.html new file mode 100644 index 00000000..7ab8e95b --- /dev/null +++ b/help/C/ch07s05.html @@ -0,0 +1,7 @@ +<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>GEL Startup Procedure</title><meta name="generator" content="DocBook XSL Stylesheets V1.79.1"><link rel="home" href="index.html" title="Genius Manual"><link rel="up" href="ch07.html" title="Chapter 7.

La forma en que se maneja es el mismo que en los bucles «for», «sum», y «prod». Si el final está dentro de <strong class="userinput"><code>2^-20</code></strong> veces el tamaño de paso del punto final, se utiliza el punto final y suponemos que no eran errores de redondeo.
