Hi, Thanks everybody for your contribution. I'm right now working with Bob's approach because:
- It handles 16 and 24 bits - The license is ok - I don't relly need top performance on those types, and the code is small. I tracked the origin of the previous code I was considering, and if anybody interested, is from a paper from Jeroen van der Zijp: ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf Clean and fast code, used by MESA. But I am not sure about the license. So, in this case of doubt, I prefer the safe side. The code suggested by James Clos (thanks Jim!) is also ok, but is under BSD license and that would mix licenses, which would be a pain for some people using the package. So, thanks again Bob, I hope integrating both formats (16 and 24 floating point) would take few days. Hopefully it will be ready for next release in July.
