They use S31.32 fixed format, which is often better precision than using floats, though it has less range. Awkward to use, but handy when you absolutely need to. I originally wrote it for MP3 decoding on ARM, but it should be portable to anything supporting "signed long long" format (hence the name). http://cvs.isoar.ca/math-sll/ -- Andrew E.
