New submission from Ellen Wang: This is only on a PowerPC, specifically a p2020, running Debian 7.0 wheezy, python 2.7.3.
Calling round() seems to corrupt something (in the floating point state?) that causes subsequent exponentiation (the ** operator) to be wrong: Python 2.7.3 (default, Jan 2 2013, 16:38:11) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> 2 ** -2 0.25 >>> round(1) 1.0 >>> 2 ** -2 0.1253019036571362 Cool. Huh? ---------- components: Library (Lib) files: math.py messages: 188033 nosy: squeakbat priority: normal severity: normal status: open title: PowerPC exponentiation and round() interaction type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file30054/math.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17865> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
