Minimally, I need addition, subtraction, multiplication, and "integer-to-real" and "real-to-integer" conversions. IEEE arithmetic would be nice, although all I require are a set of self-consistent routines. The code must execute within a 10mS control loop, so I'm willing to trade speed for accuracy, i.e. single precision is fine. Sounds like you want the Motorola 68343 Fast Floating Point software package. It used to be licensed for $500, but it's available free now from the Motorola BBS. I think the number is (512) 891-FREE. They still may want a license for commercial use. -- Eric L.
