Tom Pohl added the comment: Thanks for all the explanations why Python's floor division (FD) works as specified. And I agree, it does work as specified, but still, I think this is not the behavior that most people would expect and is therefore dangerous to provide/use.
What do I expect from FD (x//y): 1. Perform a division (I don't care about the details here). 2. Return an integer value q (even if it's stored in a float). 3. The absolute difference between the mathematical division q'=x/y and the returned result q is less than 1, since it's just a floor operation, right? 1//0.1 = 9.0 violates my personal last expectation and I guess I'm not the only one. My use case: I need to perform a division, but the method only accepts integer values, so what I used to do is FD. Since today I'm using int(x/y) or floor(x/y). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16460> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
