Mark Dickinson e979ec8fbf Issue #8986: erfc was raising OverflowError on Linux for arguments in
the (approximate) range (-27.3, 30.0), as a result of an escaped errno
value.

Mark Dickinson 6ab635a4f4 Issue #5593: Use more robust test for double-rounding in test_fsum.
While we're at it, use new unittest.skipUnless decorator to
implement skipping for that test.

Mark Dickinson 0f6414a0d6 Rename testSum to testFsum and move it to proper place in test_math.py 2008-07-31 14:48:32 +00:00
Mark Dickinson fef6b13c32 Rename math.sum to math.fsum 2008-07-30 16:20:10 +00:00
Mark Dickinson ff5f16e4e5 More modifications to tests for math.sum: replace the Python
version of msum by a version using a different algorithm, and
use the new float.fromhex method to specify test results exactly.
2008-07-29 18:45:38 +00:00
Mark Dickinson 3e9c60c5fe Remove math.sum tests related to overflow, special values, and behaviour
near the extremes of the floating-point range.  (The behaviour of math.sum
should be regarded as undefined in these cases.)

that exhibit the problem described in issue #2937.

Mark Dickinson f8476c1573 Issue #2487. math.ldexp(x, n) raised OverflowError when n was large and
negative; fix to return an (appropriately signed) zero instead.

Mark Dickinson d6d5148b44 Add test for tanh(-0.) == -0. on IEEE 754 systems 2008-04-20 20:38:48 +00:00
Mark Dickinson cec3f138d8 Yet more explicit special case handling to make
math.pow behave on alpha Tru64.  All IEEE 754
special values are now handled directly; only
the finite**finite case is handled by libm.

Mark Dickinson 9f99d70513 Report additional diagnostic information in
test_math, to help track down debian-alpha
buildbot failure.
2008-04-20 01:22:30 +00:00
Mark Dickinson e941d97d12 Additional tests for math.pow, and extra special-case
handling code in math.pow, in the hope of making all
tests pass on the alpha Tru64 buildbot.

Christian Heimes 6f34109384 I finally got the time to update and merge Mark's and my trunk-math branch. 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 :)

Jeffrey Yasskin ca2b69f765 Move __builtins__.trunc() to math.trunc() per
http://mail.python.org/pipermail/python-dev/2008-January/076626.html and issue
1965.
2008-02-01 06:22:46 +00:00
Jeffrey Yasskin 9871d8fe22 Continue rolling back pep-3141 changes that changed behavior from 2.5. This
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.
2008-01-05 08:47:13 +00:00
Jeffrey Yasskin 737c73f96f Make math.{floor,ceil}({int,long}) return float again for backwards
compatibility after r59671 made them return integral types.
2008-01-04 08:01:23 +00:00
Christian Heimes eebb79cc69 Added copysign(x, y) function to the math module 2008-01-03 22:32:26 +00:00
Christian Heimes e2ca4245c9 Added math.isinf() and math.isnan() 2008-01-03 20:23:15 +00:00
Jeffrey Yasskin 2f3c16be73 Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
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.

Raymond Hettinger 866964c3a3 Apply SF patch 652930: Add optional base argument to math.log(x[, base]). 2002-12-14 19:51:34 +00:00
Barry Warsaw 408b6d34de Complete the absolute import patch for the test suite. All relative
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.
2002-07-30 23:27:12 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
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. :)

Tim Peters a40c793d06 Rework the way we try to check for libm overflow, given that C99 no longer
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.
