Many routines in the Intel® oneAPI DPC++/C++ Compiler Math Library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
The mathimf.h header file includes prototypes for Intel® oneAPI DPC++/C++ Compiler Math Library functions.
The 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);
