%description
Header-only library for conversion to/from half-precision floating point formats

* Supports IEEE and ARM alternative half-precision floating-point format
  *  Property converts infinities and NaNs
  *  Properly converts denormal numbers, even on systems without denormal
     support
* Header-only library, no installation or build required
* Compatible with C99 and C++11
* Fully covered with unit tests and microbenchmarks
