Nick Coghlan added the comment: There is indeed a regression in decimal.localcontext with the C accelerator: omitting the argument entirely still works, but passing None explicitly now fails. I created #15783 for that.
On the topic of this thread, I'm also -1 on conversion methods, but +1 on string formatting support. There's an obvious benefit in providing the latter in order to get a better "feel" for the value of a rational number by displaying a Decimal approximation, but questionable benefit in providing the former. Explicit conversion is sufficiently rare that I'm OK with the idea of either going via a string (as used to be necessary for binary floats) or by explicitly casting the numerator to Decimal, then dividing by the denominator (no need to cast them both). ---------- nosy: +ncoghlan _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15136> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
