New submission from Philippe Rouquier: Hi,
the following statement yields different results in python2 and python3: 284397269195572115652769428988866694680//17 - int(284397269195572115652769428988866694680/17) In python3 it yields: 309657313492949847071 In python2 it yields: OL Python2's result seems to be correct as (284397269195572115652769428988866694680//17) and (int(284397269195572115652769428988866694680/17)) should return the same result (as far as I understand). With smaller numbers, this difference in results does not appear with python3. Note: I noticed this, while working on RSA; 284397269195572115652769428988866694680 is (p-1)(q-1) and 17 is e. I just mention this in case it could help. I used linux version 3.3.3.0 and 2.7.3 for the tests on a 64 bits processor. Sorry if I am missing something here. ---------- components: Interpreter Core messages: 187623 nosy: Philippe.Rouquier priority: normal severity: normal status: open title: Different division results with / and // operators with large numbers type: behavior versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17821> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
