[issue22090] Decimal and float formatting treat '%' differently for infinities and nans.

R. David Murray added the comment: Well, we have a goal of keeping the stable buildbots green. If something turns one or more red, it should either be fixed promptly, or the changeset that turned it red backed out until a fix is ready. The reason for keeping them green is so we know right

Stefan Krah added the comment: The revisions that cause the bot to go red (6c468df214dc and 227ce85bdbe0) are quite recent, so I suggest we address the failure in #22285. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22090

R. David Murray added the comment: I'm not going to argue this any further, but recent is exactly the point...if all of the bots had turned red you'd understand that it needed to be fixed *immediately* or the triggering change (regardless of what the actual bug was) backed out. Since it

[issue22090] Decimal and float formatting treat '%' differently for infinities and nans.

Stefan Krah added the comment: I think only the builders --with-system-libmpdec fail. That's inevitable, since they still use libmpdec-2.4.0. Starting from 7fbb912c0789 they should fail building _decimal entirely until I upgrade the system libmpdec on the builders. --

Stefan Krah added the comment: It seems _decimal is imported even if _decimal.so is not built. I've opened #22280 for that. Regarding this patch, everything looks fine to me. -- status: open - closed ___ Python tracker rep...@bugs.python.org

[issue22090] Decimal and float formatting treat '%' differently for infinities and nans.

Stefan Krah added the comment: I'm not sure that I understand. IMHO this issue does not break any buildbots. The current situation is that it exposes an unrelated import issue (#22280). I can camouflage that issue by upgrading the FreeBSD and the Fedora bot to libmpdec-2.4.1 (once it's out),

Stefan Krah added the comment: Thanks. I agree about 2.7 -- including 3.4 would perhaps make external libmpdec management easier for Debian and Arch. I'm not suggesting that we should always consider the distributors, but this particular issue seems so minor. --

Mark Dickinson added the comment: The decimal.py part LGTM. (The rest looks good, too, but I haven't tested it.) This seems like one of those bugs that probably isn't worth backporting to 3.4, but given the projected longevity of 2.7 it might be worth applying there. --

[issue22090] Decimal and float formatting treat '%' differently for infinities and nans.

New submission from Mark Dickinson: There's a minor inconsistency between Decimal and float formatting for the `%` format type when handling infinities and nans: from decimal import Decimal format(float('inf'), '.2%') # includes trailing '%' 'inf%' format(Decimal('inf'), '.2%') # no

Eric V. Smith added the comment: I agree that Decimal is wrong here. PEP 3101 says the result should include the trailing '%'. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22090 ___
