C99 Macros

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)
