7.1. Numerical Comparison Operators
Perl supplies the user with 6 numerical comparison operators which test for the comparison of two numbers. They are:
$a == $b | $a and $b are equal. |
$a > $b | $a is greater than $b |
$a < $b | $a is lesser than $b |
$a >= $b | $a is greater or equal to $b |
$a <= $b | $a is lesser or equal to $b |
$a != $b | $a is not equal to $b |
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 $a (1 .. 100) { if (($a % 3) != 0) { print $a,"\n"; } }
