Standard library header <stdfloat> (C++23)

This header is part of the type support library, providing fixed width floating-point types.

Types
(C++23)(optional)
 binary floating-point type with width of exactly 16, 32, 64, and 128 bits respectively
(typedef)
(C++23)(optional)
 brain floating-point type with 16 bits exactly
(typedef)

  #endif
  #if defined(__STDCPP_FLOAT64_T__)
    using float64_t  = /* implementation-defined */;
  #endif
  #if defined(__STDCPP_FLOAT128_T__)
