These two modules failed to generate much interest in
incorporating them into Phobos, but I'm still rather proud of
them :-)
So am I, the halffloat is much faster than any other
implementation I've seen. The fast path for the conversion
functions involves only a few machine instructions.
I had an extra speedup for it that made it optimal, but it
requires a language primitive to dump excess hidden precision. We
still need this, it is a fundamental operation (C tries to do it
implicitly using "sequence points", but they don't actually work
properly).
Here they are:
◦sargon.lz77 - algorithms to compress and expand with LZ77
compression algorithm
◦sargon.halffloat - IEEE 754 half-precision binary floating
point format binary16
I'll be adding more in the future.
