A partial implementation of fixed-point in a Boost-like style based on proposal N3352 is now available. <big snip>
I'm a bit surprised I didn't see this work before.
This is it's first 'public' outing.
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
We have referenced the first paper (see References section - or search the pdf for the authors name or p number), but the second was too recent for my update process ;-) There are a lot of similarities, but handling overflow etc efficiently without C/C++ access to the machine's carry bit looks difficult to me.
I will notify SG14 in case they missed your work too.
Thank you. Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830
