Finding GNU G++ counterparts of math.hpp


Hi,
I am porting a windows app written in BCB to Linux running GNU G++, there is a header file in vcl which is called math.hpp and providing the isNAN() function, so what is the closest "matchup" in GNU G++ to that file? (so I meant programmatically), not a hit in google
Thanks
Jack

I found the declaration of NAN, it is 0.0/0.0
I am scared that this will blow up at runtime, or will it?
I found the encoding scheme for NAN on Intel machines. But I don't really want to use it... it is very specific to Intel machines only
Thanks
Jack

Where should you normally look when you come across a derivation like
class a : public TForm
{
};
to Linux GNU G++
Is there a good book or any links?
Thanks
Jack

gcc doesn't have GUI forms; it has the standard stuff, plus POSIX libraries. You'll need something like Qt, GTK, or OpenGL to make GUIs. Each have their own documentation and tutorials.
