modulus operator

[Guest_imported]

Is this typical behaviour for the perl modulus operator? I assume it's something to do with the size of the number.

#!/usr/local/bin/perl -w

use strict;

print abs(-6767389730); #this prints 6767389730
print "\n";
print abs(-6767389730) % 10; #this prints 5 !
print "\n";

i don't know where you are testing, but the moduilus prints 0 on my machine..


the % operator is supposed to give you the remainder of the first number divided by the second.

try doing $var = abs(-6767389730) % 10;
then print $var;

% may be a string modifier. You shouldn't do math in a print statement anyway.
