This is a C++ header-only library to provide an IEEE-754 conformant
half-precision floating point type along with corresponding arithmetic
operators, type conversions and common mathematical functions. It aims
for both efficiency and ease of use, trying to accurately mimic the
behaviour of the builtin floating point types at the best performance
possible. It automatically uses and provides C++11 features when
possible, but stays completely C++98-compatible when neccessary.
