I prepared a sub from the FAQs and I can't get it to work. I want to make sure there are 2 decimal points and comma the number in the same subroutine. For some reason, the number isn't coming back accurately.

Alone, each of these work. Together, the number gets jumbled. Any idea as to why?

sub numfix 
{
   my $num  = shift;
   1 while $num =~ s/^([-+]?\d+)(\d{3})/$1,$2/;
   $num = sprintf("%.2f", $num);
   return $num;
}
