From e82ac51cd6b09a5dfb3803a0cd21c7ea95ac0e15 Mon Sep 17 00:00:00 2001 From: Mark Dickinson Date: Tue, 29 Dec 2009 20:52:27 +0000 Subject: [PATCH] Merged revisions 77116 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk ........ r77116 | mark.dickinson | 2009-12-29 20:51:24 +0000 (Tue, 29 Dec 2009) | 6 lines Issue #7575: An overflow test for math.expm1 was failing on OS X 10.4/Intel, due to a defect in the platform's implementation of expm1. Since the issue is of low severity, and appears to be fixed in OS X 10.5 and 10.6, it doesn't seem worth working around, so I'm just weakening the relevant test so that it passes on 10.4. ........ --- Lib/test/math_testcases.txt | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/Lib/test/math_testcases.txt b/Lib/test/math_testcases.txt index bd8813eaf8..21730df720 100644 --- a/Lib/test/math_testcases.txt +++ b/Lib/test/math_testcases.txt @@ -396,8 +396,14 @@ expm10215 expm1 -1.79e308 -> -1.0 -- extreme positive values expm10300 expm1 300 -> 1.9424263952412558e+130 expm10301 expm1 700 -> 1.0142320547350045e+304 -expm10302 expm1 709.78271289328393 -> 1.7976931346824240e+308 +-- the next test (expm10302) is disabled because it causes failure on +-- OS X 10.4/Intel: apparently all values over 709.78 produce an +-- overflow on that platform.
