Hi,

I'm working on a proposal that would add functions for integer
division in various rounding modes:

https://isocpp.org/files/papers/D3724R0.htm

This is something I actually wanted to write years ago, but I was
under the false impression that SG6 is already working on this
problem. In reality, the proposal P0105R1 which last worked on this
was abandoned a long time ago.

Anyway, please share your thoughts :)

Inspired by this paper I added a subset of this functionality to https://github.com/HowardHinnant/bbi
with this commit:  https://github.com/HowardHinnant/bbi/commit/cb729817de0dc64b1510f3d25df332c6c2362e2c
