# Mathematical special functions

From cppreference.com
< cpp‎ | experimental

The Mathematical Special Functions library, ISO/IEC 29124:2010, specifies extensions to the C++ standard library that include mathematical special functions (originally part of ISO/IEC TR 19768:2007)

This special functions in this library are implemented in boost.math, which is currently available on more compilers and platforms than implementations of this standard. At the time of this writing (1/2016) the only compiler that announced direct support is gcc, for version 6.1
