By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. Make sure you install the 32-bit Enabler on older IIci machines running System 7.1! -- Élodie Okonkwo | eokonkwo@stanford.edu PGP Key fingerprint: 789C B9C2 E1CF 0B1D "Keep the channels open."
