C99 fenv.h for MS compilers

880 views Asked by At

Anyone know of a decent C99 fenv.h implementation for MS compilers?

I imagine this wouldn't be difficult to do; I'm just looking to save some time.

I don't know of any implementations and I doubt any exists. Although Visual Studio has the _controlfp() function and a number of related preprocessor pragma's (float_control(), fenv_access(), fp_contract(), I don't think you can use them to create a conforming fenv.h implementation.

Sad as it is, Visual Studio is not a C99 compiler, and probably never will be.
