+<p><div class="box">
+
+<dl>
+<dt><nobr>(/= <i>expr1</i> <i>expr2</i> ...)</nobr></dt>
+<dd><i>exprN </i> - a numeric expression<br>
+returns - <a href="t.htm">&nbsp;T&nbsp;</a> if the results of

+
+<h2>Description</h2>
+
+<p>The <nobr>'/=' [not-equal]</nobr> function takes an arbitrary number of
+numeric arguments. It checks to see if all the numeric arguments are
+different. <a href="t.htm">&nbsp;T&nbsp;</a> is returned if
+the arguments are numerically not equivalent,
+<a href="nil.htm">NIL</a> is returned otherwise.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(/= 1 1)            =&gt; NIL
+(/= 1 2)            =&gt; T
+(/= 1 1.0)          =&gt; NIL
+(/= 1 2 3)          =&gt; T
+(/= 1 2 2)          =&gt; NIL
+(/= "a" "b")        =&gt; <font color="#AA0000">error: bad argument type</font>
+(setq a 1 b 12.4)   =&gt; 12.4  <font color="#008844">; set up A and B with values</font>
