Are there any math packages that implement "fixed point" higher math functions? (or not so high, for that matter.) As far as I know, everyone who's ever implemented a SINE function for their 8bit number, 8bit fraction fixed point numbers has done it themselves. Likewise the 6bit number with 2bit fraction, and so on. Even multiplication and division become slightly more complicated than traditional math...
