If that ever helps, I implemented this fast conversion
ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf for a
half wrapper here:
https://github.com/p0nce/gfm/blob/master/math/half.d
It's woefully untested though.
In 3D graphics efficiently converting float to half can speed up
vertex submission.
Thanks, I read the paper. It looks interesting. I did notice, however, that it
does not appear to do IEEE rounding correctly (unless I misunderstood the code),
nor does it have any hooks for detection of Inexact, Underflow and Overflow.
These come into play when converting a float to a half.
