warning STL4038: The contents of <stdfloat> are available only with C++23 or later. #238
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\include\stdfloat(12): warning STL4038: The contents of <stdfloat> are available only with C++23 or later.
In addition to checking for the header, the version of the standard should also be checked. Here is how the same warning was fixed in Boost.Math: https://github.com/boostorg/math/pull/1024/files
