Actually any string ending in INF is more appropriate than any string beginning with INF. Since
negative infinity evaluates to "-INF" but it is still infinite. However in either case
the STRING "INF" is not infinite, only a float that converts to "INF" or
"-INF" is infinite.
A more appropriate function might be:
<?php
if (!is_defined('is_infinite')) { function is_infinite($val) {
return (is_float($val) and ("$val"=='INF' or
"$val"=='-INF'));
} }
?>
* However the above function is untested.
