Tim Peters <[email protected]> added the comment:
GMP's mpz has 18 functions of this form. These are the 6 "ceiling" flavors:
c_divmod
c_div
c_mod
c_divmod_2exp
c_div_2exp
c_mod_2exp
The suggestion here is for c_div.
There are 6 more for floor rounding (with prefix "f_" instead of "c_"), and
another 6 for truncation ("to-zero" rounding, with prefix "t_"). Curiously
enough, there's no direct support for any form of "round to nearest".
So that's where this ends ;-)
I personally almost never use -(-x // y). Because it's a bit obscure, and in
real life y is always known to be positive, so the nearly obvious (x + y - 1)
// y works fine.
