My question wasn't clear. I know that rand() returns a number between 0 and it's argument. But my point was, it returns a decimal; i.e. 3.14159, 25.70098, .00001, etc. Does perl automatically round the number down(or take the integer portion)? For eaxample, here is my code:

    my $lRandomPassword = '';
    my $lMaxLength = 10;
    my $length;
    my $lRand;
    my @lKeySpace = ('A'..'Z', 'a..z', 0..9);
    my $lKeySpaceSize = scalar(@lKeySpace);
    for ($length = 0; $length < $lMaxLength; $length++) {
        $lRand = int(rand($lKeySpaceSize));
        $lRandomPassword .= $lKeySpace[$lRand];
    };
    $lRandomPassword;

Yes, I know the code is overly verbose, but the important question for me is, could I safely get rid of the int() call? Does perl take the integer portion of an array index?
