> I confess that I've no idea what the "without overflow check" bit means After some digging, it is indeed to do with the int/long unification: - In Python 2.1, arithmetic operations on ints would raise OverflowError on overflow. - Except that left shift did not raise: shifted out bits were simply lost. This is described in PEP 237. In Python 2.2, arithmetic operations (including left shift) were changed to produce a long instead of overflowing. The "without overflow check" part of the doc almost certainly refers to the Python 2.1 behaviour (at least for left shift; I'm guessing that for right shift, where overflow isn't possible, this was just a redundant copy-paste), and was never updated. It should be removed for both left shift and right shift. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39301> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
