From wagnerc: >That's all good for rounding intermediate numbers in a calculation... 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.
