WebFeb 21, 2024 · There are lots of assembly-language questions on Stack Overflow about how to implement large divisions in terms of a 2N / N => N-bit division. (C++ of course doesn't have that, just use a 2N bit type and let your compiler (fail to) optimize it.)

WebAug 2, 2024 · The IEEE standard also specifies half-precision (2-byte) and quadruple-precision (16-byte) formats, and a double-extended-precision (10-byte) format, which some C and C++ compilers implement as the long double data type. In the MSVC compiler, the long double data type is treated as a distinct type, but the storage type maps to double.
