> Initial implementation. Some notes in the current implementation in the PR: the impetus for the change is to provide a minimal level of platform support for the binary16 floating-point format defined in IEEE 754. This is done by added two methods to Float, one for binary16 -> float conversion and the other for float -> binary16 conversion. In the absence of the ability to define primitive types, short is used as a carrier for the bits of a binary16 value. The conversion code in its current form favors readability over speed; a more performant software implementation may be possible even without intrinsification. A different 16-bit floating-point format, bfloat, is popular in some circles. Any similar support for bfloat will be left for future work.
