I'm writing a utility for work that will calculate the price to send a

I'm trying to round weights (with up to two decimal places) up to the
next half kilo (unless the weight is an exact or .5 kilo already).
I think you are making this waaaay to complicated.
For one I am pretty sure there are modules on CPAN that do floor() and
ceiling() functions.
And second there are really only three simple cases that you need to
distinguish:
if the decimal portion is 0 then the shipping weight is the actual weight
If 0 < decimal portion <= 0.5 then the shipping weight is the integer part
plus 0.5
If 0.5 < decimal portion then the shipping weight is the integer part plus 1
