Hi,

I'm a bit surprised I didn't see this work before.
Are you aware that SG14, the gamedev, real-time simulations, embedded
software and financing study group for the standard
is working on fixed point real proposal too?
Here is a version of the proposal:
http://johnmcfarlane.github.io/fixed_point/papers/p0037r2.html and
http://johnmcfarlane.github.io/fixed_point/papers/p0381r0.html
I will notify SG14 in case they missed your work too.
