The Mathematical Special Functions library was originally part of Library TR1 ISO/IEC TR 19768:2007, then published as an independent ISO standard, ISO/IEC 29124:2010, and finally merged to ISO C++ as of C++17.
SeeMathematical special functions for the ISO/IEC 29124:2010 version of this library.

Thefloat andlongdouble overloads for math special functions without the "f" or "l" suffix are present in the final draft of ISO/IEC 29124:2010 (N3060), but absent in the published C++17/20 standard (seeLWG issue 3234). These overloads were not provided by MSVC STL until VS 2022 17.3.
These functions are unrelated tospecial member functions of class types.
