How can this be done in assembly? Because there is no way to raise a number by .5 is there?

consult any book/tutorial on FPU commands (the easiest way to do the thing), they all start with "f"
you will need basically fld (fild), fsqrt, fst (fist)

Are you gonna use the FPU or not?

If you're limited to integers, it *might* be practical to use a table instead... "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."
