Use the modulo operator %. Given integers $x and $y, the expression $x % $y gives the remainder when $x is divided by $y. As a result, if (and only if) $x is exactly divisible by $y, $x % $y is equal to 0. #!perl use 5.010; # for 'say' say 5 % 2; say 6 % 2; say 7 % 2; say 79 % 40; say 80 % 40; say 81 % 40; For more information, see http://perldoc.perl.org/perlop.html#Multiplicative-Operators Phil -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
