How to test is a string is a multiple of 4 2

[learingperl01]

Hello, wondering how to go about testing a string to see if it's a multiple/multiplier of 4. I want to be able to ensure that the string that I am working with is always going to be able to be divided by four if not then I would like to ignore it.

thanks for the help in advanced.

if ( ($n / 4) <= 0 ) {
    print "$n is not divisible by four: $dv\n";
}
else {
    print "$n is divisible by four: $dv\n";
}

Wish I could edit...

main point is:

if ( ($n / 4) <= 0 ) {

Modulus operator '%' returns the remainder of division. You can use that to test for a true/false return value:

if ($n % 4) {
  print "Not divisor of 4 because there is a remainder\n";
}
