New submission from Manuel Jacob: When evaluating, signed zero complex numbers aren't recovered correctly. >>> -0j (-0-0j) >>> (-0-0j) 0j >>> 0j 0j
According to http://docs.python.org/dev/reference/datamodel.html#object.__repr__ the representation can be used to recreate an object with the same value. Shouldn't this also be possible with complex numbers? When using complex('...'), round-trip works correctly. While this can be used to recover the exact number, i find it confusing that complex('...') isn't the same as eval('...'). >>> complex('-0j') -0j >>> complex('(-0-0j)') (-0-0j) >>> complex('0j') 0j ---------- messages: 183313 nosy: mjacob priority: normal severity: normal status: open title: Complex number representation round-trip doesn't work with signed zero values type: behavior versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17336> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
