I don't know if C++ has reached any conclusions about what form C++ support for such types should take, but my expectation was that something library-based, similar to the support for decimal floating-point types, might be used. > Or maybe ISO/IEC JTC1 SC22 WG14 N2016[2] is a better way for > half-precision data types? No. short float has been specifically rejected in WG14, given the expectation that people using narrower-than-float types will want a specific format (whether binary16 or bfloat16) rather than something more generic where they don't know what format it has. -- Joseph S.
