half: half (HALF-PRECISION FLOATING POINT LIBRARY) half: half: This is a C++ header-only library to provide an IEEE 754 conformant half: 16-bit half-precision floating point type along with corresponding half: arithmetic operators, type conversions and common mathematical half: functions. It aims for both efficiency and ease of use, trying to half: accurately mimic the behaviour of the builtin floating point types at half: the best performance possible. half: half: half:
