note 102541 added to function.is-int

I noticed that is_int(sqrt(16)) is false, and I wanted the sqrt to really return an int if it was an int.

So I wrote 
<?php
	function is_really_int(&$val) {
		$num = (int)$val;	
		if ($val==$num) {
			$val=$num;
			return true;
		}
		return false;
	}
?>

You'll may criticise the side effects but I don't think they hurt.
