Nettet10. feb. 2024 · Typedef names of the form intN_t may only be defined if the implementation supports an integer type of that width with no padding. Thus, std::uint24_t denotes an unsigned integer type with a width of exactly 24 bits. Each of the macros listed in below is defined if and only if the implementation defines the corresponding typedef name.
