C99 Macros

Many routines in the Intel® Math Library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.

The mathimf.h header file includes prototypes for Intel® Math Library functions.

The Intel® Math Library and mathimf.h header file support the following C99 macros:

int fpclassify(x);
int isfinite(x);
int isgreater(x, y);
int isgreaterequal(x, y);
int isinf(x);
int isless(x, y);
int islessequal(x, y);
int islessgreater(x, y);
int isnan(x);
int isnormal(x);
int isunordered(x, y);
int signbit(x);
