Mark Dickinson 47a84aa978 Move asinh documentation to the proper place. 
Remove meaningless 'in radians' from inverse
hyperbolic functions.

Mark Dickinson 48f7a4aabb Correct documentation for math.pow; 
0**nan is nan, not 0.  (But nan**0 and 1**nan are 1.)

Also fix minor typo: 'quite NaN' -> 'quiet NaN'

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.

Georg Brandl 9749e15e2f Remove with_statement future imports from 2.6 docs. 2008-01-05 19:28:16 +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.

Andrew M. Kuchling 54966a5f94 Fix markup 2008-01-04 18:25:05 +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.
