<refpurpose>
Converts a string to a signed integer (k-rate).
</refpurpose>

<refsect1>
<title>Description</title>
<para> Convert a string to a floating point value at i- or k-rate. It is also possible to pass an strset index or a string p-field from the score instead of a string
argument. If the string cannot be parsed as a floating point or integer number, an init or perf error occurs and the instrument is deactivated.
<note>
<title>Note</title>
<para>If a k-rate index variable is used, it should be
valid at i-time as well.
