This manual was written on Mac, so all figures refer to Mac version; but there are equivalent to the Win95 ones.
This app is interely written in C, using standard "C" and standard well known API on both Mac and Windows.
It has an unique source, with some conditional #defines for both platform.
It was fine tuned for best performance on both platforms. The mac version is 'FAT' so will run on every Mac. (I compiled for old 68000 too!).
P.S. You are encouraged to send reports about timing of a standard function x*sinx in range -100 <x <100 with 10'000 points: We will compile a ranking.
