Mark Dickinson 99d652ef66 Issue #7534: Fix handling of nans, infinities, and negative zero in **
operator, on IEEE 754 platforms.  Thanks Marcos Donolo for original patch.
2009-12-30 12:12:23 +00:00
Mark Dickinson 31f0cfef0e Include ieeefp.h (when available) in pyport.h instead of individually in
Objects/floatobject.c and Objects/complexobject.c.  This should silence
compiler warnings about implicit declaration of the 'finite' function
on Solaris.

Mark Dickinson bd15a06fd3 Issue #7117, continued: Change round implementation to use the correctly-rounded
string <-> float conversions;  this makes sure that the result of the round
operation is correctly rounded, and hence displays nicely using the new float
repr.

Eric Smith a985a3aee4 Issue #5920: Changed format.__float__ and complex.__float__ to use a precision of 12 when using the empty presentation type. This more closely matches str()'s behavior and reduces surprises when adding alignment flags to an empty format string. Patch by Mark Dickinson. 2009-05-05 18:26:08 +00:00

Eric Smith 068f06568b Issue #5835, deprecate PyOS_ascii_formatd.
If anyone wants to clean up the documentation, feel free. It's my first documentation foray, and it's not that great.

Will port to py3k with a different strategy.

in the spirit of 3.0 are available via a #define only.  See the email thread.

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 :)

across platforms:  it should now raise OverflowError on all

non IEEE 754 platforms.)

Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.

Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Christian Heimes 422051a367 Patch #1953
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

Neal Norwitz 5f95a79b2b Add prototypes to get the mathmodule.c to compile on OSF1 5.1 (Tru64)

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.

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.
