c++ - Re: Complex numbers for DOSX

Hi Walter,

Is it difficult to enable complex number stuff (per C99) in DOSX model
either?

The only problem you mentioned in CTG is the fact that under DOSX
coprocessor may not present.

What about enabling complex number feature for DOSX for CPU target 5
(Pentium) and above? Since P5 all processors have FPU integrated. And if
not, this is problem of developer to provide system-level support for
coprocessor.

What do you think?

Looking forward for your answer,
Nic Tiger.

P.S. By the way, using complex numbers with simplicity you provided is
great!

That means two runtime libraries would have to be supplied. It's doable, but
just a lot of work.

Do you mean 2 libraries DOSX and WIN32 or you mean DOSX 5+ and 3+ ?

I think complex number stuff can be separated in different lib (
complex.lib, e.g.) and the only support is needed is from compiler to
compile with -mx -5 (+) using complex. The rest of the standard library
will stay unmodified. Am I right? Or something prevents using this way?

Nic Tiger.

P.S. I have DMC CD with all RTL sources and can help you in porting complex
number stuff from WIN32 library to DOSX library.
