Yep, you're right. > What about for values such as 1.2304? Again the 'modulus' > version yields 1.23, whereas the 'regex' version this time > gives 1.230.

And at this point we're in a position where no printf format will help; there's no way to get printf to round the way we'd want to. Basically at this point comes down to writing a custom stringification.. or looking for one on CPAN, at least. -- Regards, Aristotle "If you can't laugh at yourself, you don't take life seriously enough."
