I've been using this subroutine for a while to add commas to a number, and truncate the decimal point & remainder. For some reason, it's not working for one of my scripts, while it's working perfectly fine in others. Can anyone see why the following code might not work? 
my $testNumber = 123456.789;
$testNumber = addComma($testNumber);
print $testNumber;

sub addComma {
    my $number = $_[0];
    $number = reverse $number; 
    $number =~ s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g; 
    $number = reverse $number;
    return $number;
}

returns:
123,456.789

Any help would be greatly appreciated.

Thx, monks!
