It could be slightly more efficient (no div instructions to divide by 100, but shifts to divide by 256) when the second one isn't expressed in the range [0, 100) but [0, 255). Also it feels like there is a mismatch of precision of the divided-by-100 result when using 8 bits for the fraction (only 100 out of the 256 possible fractions are used). Small thing, but easy to do. -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/xs4all.nl -- are condemned to reinvent it. Poorly.
