Mike, Thanks for your confirmations of these bugs. Just to clarify: I trust you agree that all these cases are buggy except for (expt 10 -300) and (integer-decode-float 1.0) (which both crash on my machine, but give the correct answers on Mike's and Camm's). I should have mentioned that I was using the most recent prebuilt binary (gcl_2.5.0.cvs20021220_mingw32), running on a 1GHz Athlon under Windows 2000. Is it possible the Athlon is the issue in the cases where my result is different from yours? Does GCL use GMP even for purely floating-point operations like decode-float? Does GCL or GMP use architecture-specific instructions (gcc -march etc.?). -s
