It's an IEEE standard format:

http://en.wikipedia.org/wiki/Half-precision_floating-point_format#IEEE_754_half-precision_binary_floating-point_format:_binary16

This is what I see:

writeBin(vec , con, size=2 )
Error in writeBin(vec, con, size = 2) : size 2 is unknown on this machine

I'm not sure what the machine has to do with it. It's really up to the software, isn't it?

Is there a way to get R to read/write half-precision numbers (binary16)?

It isn't a big deal for me because unsigned 16-bit integers are working well enough, but I'd like to have an answer for people who ask why I make them divide by 1000 all the time. ;-)
