note 29709 added to ref.math

Theres another faster way of doing even/odd number checking by using bitwise operators. Don't ask me how it works, I just found this out by experimenting with it (could the editor possibly explain?) if ((1&$num)) { echo "$num is odd"; } if (!(1&$num)) { echo "$num is even"; } How it works is (1&$num) returns a 1 for odd numbers and returns 0 when it's an even number. -- http://www.php.net/manual/en/ref.math.php http://master.php.net/manage/user-notes.php?action=edit+29709 http://master.php.net/manage/user-notes.php?action=delete+29709 http://master.php.net/manage/user-notes.php?action=reject+29709
