* I finally got the time to update and merge Mark's and my trunk-math branch. ↵Christian Heimes2008-04-181-125/+81
| | | | | | 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 :)

* Backport of PEP 3101, Advanced String Formatting, from py3k.Eric Smith2008-02-171-0/+43
| | | | | | | | | | | | | | | 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).
* Patch #1953Christian Heimes2008-02-041-7/+23
| | | | | 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

* Continue rolling back pep-3141 changes that changed behavior from 2.5. ThisJeffrey Yasskin2008-01-051-55/+3
| | | | | | | | | | | | 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.
* Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (justJeffrey Yasskin2008-01-031-26/+82

The only significant difference is that round(x) returns a float to preserve backward-compatibility. See http://bugs.python.org/issue1689.
