note 21946 added to ref.math

I found it kind of irritating that PHP had no native functionality for a calculating Factorials. Since I really didn't feel like loading the GMP library, I figured I'd write my own function. function fact($s){$r=(int)$s; for ($i=$r;$i--;$i>1){$r=$r*$i;} return $r;} I think that's right... I havn't tested it extensively but it should work. -- http://www.php.net/manual/en/ref.math.php http://master.php.net/manage/user-notes.php?action=edit+21946 http://master.php.net/manage/user-notes.php?action=delete+21946 http://master.php.net/manage/user-notes.php?action=reject+21946
