C99 Macros

Many routines in the Intel® Math Library are more 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);

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
