- Luc B. suggests that he got 1.0, but I could not duplicate the result
- using Watcom under OS/2 (I don't use DOS). When I ran the original
- program, I did not get any error message. However, when I tried to USE
- THE VALUE OF "z" (for example, writing the value on the screen), I got
- a nice error message "*ERR* KO-01 floating point divide by zero".
- Note that the original program does not use the calculated "z".
- Thus, I still believe I can use WATCOM (of course, level-B patched)
- for serious numerical work. My hardware is SWAN 486-50DX2 local bus
- system. Oh, if one suspects a hardware-related problem, I would suggest
- that he may use f2c to check whether he can duplicate the problem.
- BTW, f2c with GCC/2 2.2 is very nice and fast in floating point calc.
- Although it is a little slower than WATCOM, it is not slower than
- f2c with GCC/EMX in my experience (GCC/2 2.1 was a bit slower).
