Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. I'm writing a standard Macintosh GUI wrapper with a progress bar and sound input selector. -- === Nadia López === Dept of Electrical Engineering, Public Access Unix of New York "The carrier frequency does not drift by accident."
