[QUOTE]
I don't see the relation between 64 bit and basic floating point operations (regardless if implemented by emulation, FPU, or vector instructions) when using a C compiler.
[/QUOTE]

Well, perhaps I'm laboring under false knowledge. I have a 32 bit masm created FPU lib, i.e., fpulib.lib, which has within it the function I need, e.g., ...

FpuFLtoA(...)

...which returns through an out parameter my floating point number converted to a Z string. I can't link that 32 bit library into 64 bit code can I? I just assummed not, because of the fact 32 bit dlls can't be directly used by 64 bit binaries.

And thanks again for the information on those various functions deep in the internals of printf. I hadn't looked into that end of it deep enough to determine where they were implemented, but what you told me closes that possibility, apparently.

Where I'm at now is if I'm to use your links to download the GCC sources I apparently have to install and learn to use git. Years ago I worked with Linux some but never became terribly proficient in that world. Never could find anything comparable to the Windows Api for writing GUI apps. About the closest thing I could find that I could marginally tolerate was GTK. I liked XLib but it wasn't suitable for creating GUI apps (no controls (widgets). But unless you tell me I can link 32 bit libraries into 64 bit executables, or somehow I can come up with a 64 bit FPU lib (if I need it), I see studying the GCC sources as my only hope?
