Hi all, is there already an operator named %% (double-percent)? Somewhere in Python or its relatives?
If not, we could have the best of both worlds. Just let act in Cython % as the corresponding C operator, i.e. -1 % 5 == -1 (to have maximal speed), and let in Cython %% act as the Python % operator, i.e. -1 %% 5 == 4 (to have maximal convenience). In Python, we also have the // (double-slash) operator, which does not exist in C, so an uninitiated programmer coming across %% for the first time has a good chance of guessing what that means. And as Craig pointed out above, "descending from Python to Cython" we already have to make certain (but very few and easily remembered) changes. I then would allow %% to be used in Sage, too, just to have this unambiguous notion available. Thoughts? Cheers, gsw P.S.: As William pointed out somewhere, the meaning of 1/2 differs between different Python versions (right now I don't remember the exact details). P.P.S.: I'd vote against making this dependent on compile-time options. This leads to non-portable code (think of having to merge two code fragments relying on different choices of these options --- what a nightmare). --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
