Describe the bug
std::isnan is supposed to have an overload for all integral types. The lack of this overload triggers C2668 when called using an unsigned short.

Godbolt

Expected behavior
Call proper overload (casting to double).

Duplicate of #519

This is LWG-1327 which is #resolved in C++11. Unfortunately, the overloads are currently provided in UCRT, and a complete resolution cannot be achieved in this repo.
