I have a recollection from a computer math class many years ago that you
should never, ever, round intermediate numbers in a calculation. The
"rounding" itself then becomes part of the next step, then the next, and
so on. While that may not be an issue with simple addition/subtraction,
multiplication (or worse, exponentiation), could turn a little rounding
into a huge error at the end.
