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.
