The latter is a crude hack, and was traditionally used to save cycles when floating-point division was very slow. There are better ways, and have been for decades. > Float formatting is an entirely different issue. Not really. You need controlled rounding to a fixed precision in the other base. But I agree that controlled rounding in binary does not help with controlled rounding in decimal.
