How do I find out weather a number is odd or even?
Visitor Ratings (2) :
Description
Use the MOD (%) operator, for example like this:
$i = 10;
if ($i % 2) {
echo "$i is odd";
} else {
echo "$i is even";
}
it's suggested that one use the MOD operator, but performance wise it's much better to use the & operator, thus:
Code
Select All
$i = 10; if ( $i&1 ) { echo "$i is odd"; } else { echo "$i is even"; }
