Martin Panter added the comment: The problem is more widespread than just Power PC. The same failures (+/-29) are also seen on the three s390x buildbots. There are multiple failures of testExactPowers(Negatives) on http://buildbot.python.org/all/builders/x86%20Tiger%203.x/builds/11140/steps/test/logs/stdio
The first is AssertionError: 9.000000000000002 != 9 An slightly different failure happens on AMD64 Free BSD and Open Indiana buildbots: http://buildbot.python.org/all/builders/AMD64%20OpenIndiana%203.x/builds/11077/steps/test/logs/stdio ====================================================================== FAIL: testFraction (test.test_statistics.Test_Nth_Root) ---------------------------------------------------------------------- Traceback (most recent call last): File "/export/home/buildbot/64bits/3.x.cea-indiana-amd64/build/Lib/test/test_statistics.py", line 1247, in testFraction self.assertEqual(self.nroot(x**12, 12), float(x)) AssertionError: 1.1866666666666665 != 1.1866666666666668 ---------- title: Private _nth_root function loses accuracy on PowerPC -> Private _nth_root function loses accuracy _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27761> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
