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);
