* SF bug 705231: Assertion failed, python aborts.Tim Peters2003-05-241-0/+17
| | | | | | | float_pow(): Don't let the platform pow() raise -1.0 to an integer power anymore; at least glibc gets it wrong in some cases. Note that math.pow() will continue to deliver wrong (but platform-native) results in such cases.
* Combine the functionality of test_support.run_unittest()Walter Dörwald2003-05-011-3/+1
| | | | | | | | | | and test_support.run_classtests() into run_unittest() and use it wherever possible. Also don't use "from test.test_support import ...", but "from test import test_support" in a few spots. From SF patch #662807.
* Port test_pow.py to PyUnit. From SF patch #662807Walter Dörwald2003-02-031-124/+110

* Fix typo in abstract.c which caused __rpow__ to not be invoked.Raymond Hettinger2002-12-071-0/+5
| | | | | Added related testcase. Closes SF bug #643260.
* Get rid of relative imports in all unittests. Now anything thatBarry Warsaw2002-07-231-1/+1
| | | | | | | | | | | imports e.g. test_support must do so using an absolute package name such as "import test.test_support" or "from test import test_support". This also updates the README in Lib/test, and gets rid of the duplicate data dirctory in Lib/test/data (replaced by Lib/email/test/data). Now Tim and Jack can have at it. :)

* Revert the previous patch to test_pow.py and move the test to test_unary.pyFred Drake2001-08-301-10/+0
| | | | | based on a suggestion from Tim Peters; also make sure that we're really doing exponentiation and not multiplication.
* Added a regression test for the negation-of-exponentiation optimizationFred Drake2001-08-301-0/+11

* Update the code to better reflect recommended style:Fred Drake2000-12-121-2/+2
| | | | | Use != instead of <> since <> is documented as "obsolescent". Use "is" and "is not" when comparing with None or type objects.
* Make reindent.py happy (convert everything to 4-space indents!).Fred Drake2000-10-231-24/+24

* SF bug 115831 and Ping's SF patch 101751, 0.0**-2.0 returns inf rather thanTim Peters2000-10-061-30/+55
| | | | | | | | | | raise ValueError. Checked in the patch as far as it went, but also changed all of ints, longs and floats to raise ZeroDivisionError instead when raising 0 to a negative number. This is what 754-inspired stds require, as the "true result" is an infinity obtained from finite operands, i.e. it's a singularity. Also changed float pow to not be so timid about using its square-and-multiply algorithm. Note that what math.pow does is unrelated to what builtin pow does, and will still vary by platform.
