<kenn@remus.rutgers.edu>. This emulator does not yet emulate the following functions: FSINH, FETOXM1, FTANH, FATAN, FASIN, FATANH, FSIN, FTAN, FETOX, FTWOTOX, FTENTOX, FCOSH, FACOS, FCOS, FSINCOS It is sufficient, however, to allow programs like df, w, and newfs, to run to completion with correct results. Portions of this code were based on the sparc fpe and on initial work by gwr.
