Perl supplies the user with 6 numerical comparison operators which test for the comparison of two numbers. They are:
$x == $y | $xand $yare equal. |
$x > $y | $xis greater than $y |
$x < $y | $xis lesser than $y |
$x >= $y | $xis greater or equal to $y |
$x <= $y | $xis lesser or equal to $y |
$x != $y | $xis not equal to $y |
Those operators can be used inside conditionals and also outside, as part of a normal expression. The following program prints all the numbers between 1 and 100 that are not divisible by 3:
for $n ( 1 .. 100) { if (( $n % 3) != 0) { print $n, " \n "; } }
