The Intel® C++ Compiler includes a mathematical software library containing highly optimized and very accurate mathematical functions. These functions are commonly used in scientific or graphic applications, as well as by other programs that rely heavily on floating-point computations. To include support for C99 _Complex data types, use the /Qstd=c99 compiler option.
The mathimf.h header file contains prototypes for the math library functions. For a quick look at the complete list of the functions available, refer to the Function List.
Many routines in the libm library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
Note
See the Release Notes for changes in Windows* support for the 80-bit long double type.
