This header is part of thetype support library, providingfixed width floating-point types.
Types | ||
(C++23)(optional) | binary floating-point type with width of exactly 16, 32, 64, and 128 bits respectively (typedef)[edit] | |
(C++23)(optional) | brain floating-point type with 16 bits exactly (typedef)[edit] | |
The fixed width floating-point types must be aliases to extended floating-point types (notfloat /double /longdouble), therefore not drop-in replacements for standard floating-point types.
