* I finally got the time to update and merge Mark's and my trunk-math branch. ↵Christian Heimes2008-04-181-3/+238
| | | | | | The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math. The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
* Move __builtins__.trunc() to math.trunc() perJeffrey Yasskin2008-02-011-0/+31

* Continue rolling back pep-3141 changes that changed behavior from 2.5. ThisJeffrey Yasskin2008-01-051-4/+4
| | | | | | | | | | | | round included: * Revert round to its 2.6 behavior (half away from 0). * Because round, floor, and ceil always return float again, it's no longer necessary to have them delegate to __xxx___, so I've ripped that out of their implementations and the Real ABC. This also helps in implementing types that work in both 2.6 and 3.0: you return int from the __xxx__ methods, and let it get enabled by the version upgrade. * Make pow(-1, .5) raise a ValueError again.
* Make math.{floor,ceil}({int,long}) return float again for backwardsJeffrey Yasskin2008-01-041-0/+8

* Added copysign(x, y) function to the math moduleChristian Heimes2008-01-031-0/+7

* Added math.isinf() and math.isnan()Christian Heimes2008-01-031-0/+16

* Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (justJeffrey Yasskin2008-01-031-0/+26
| | | | | | | the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361, r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new documentation. The only significant difference is that round(x) returns a float to preserve backward-compatibility. See http://bugs.python.org/issue1689.

* Complete the absolute import patch for the test suite. All relativeBarry Warsaw2002-07-301-1/+1
| | | | | | | | imports of test modules now import from the test package. Other related oddities are also fixed (like DeprecationWarning filters that weren't specifying the full import part, etc.). Also did a general code cleanup to remove all "from test.test_support import *"'s. Other from...import *'s weren't changed.
* 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. :)

* Rework the way we try to check for libm overflow, given that C99 no longerTim Peters2001-09-051-1/+1
| | | | | | | | | | | | | | | requires that errno ever get set, and it looks like glibc is already playing that game. New rules: + Never use HUGE_VAL. Use the new Py_HUGE_VAL instead. + Never believe errno. If overflow is the only thing you're interested in, use the new Py_OVERFLOWED(x) macro. If you're interested in any libm errors, use the new Py_SET_ERANGE_IF_OVERFLOW(x) macro, which attempts to set errno the way C89 said it worked. Unfortunately, none of these are reliable, but they work on Windows and I *expect* under glibc too.
