even number detecting?

[Tandem]

Hi, i need some way to be able to detect whether a number is even or not. I searched the php manual but couldn't find anything that does this.

Anyone know of a way to do this?

modulus operator - http://ca.php.net/operators.arithmetic

[code]<?php
$num = 4; // example
if ($num%2) {
    echo "odd";
} else {
    echo "even";
}
?>[/code]

Thanks, i'll give this a try.
