Math Function List

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 functions are listed here by function type.

FP16 Math Functions have the following requirements:

Version 2021.4 or higher of the Intel® oneAPI DPC++/C++ Compiler.

A next-generation Intel® Xeon® Scalable processor, code name Sapphire Rapids.
