I'm trying to round weights (with up to two decimal places) up to the

For one I am pretty sure there are modules on CPAN that do floor() and
ceiling() functions.
There are that, and, IIRC (from today's Googling for a round() function)
they are part of POSIX, and therefore (if my understanding is correct)
already installed.
Trouble is, I don't know what those are/do, perldoc wasn't much help,
I suppose they're mathematical functions, I didn't get that far with my
education and so didn't understand,
