Issue #5816 :
...
- simplify parsing and printing of complex numbers
- make complex(repr(z)) round-tripping work for complex
numbers involving nans, infs, or negative zeros
- don't accept some of the stranger complex strings
that were previously allowed---e.g., complex('1..1j')

Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names
in the spirit of 3.0 are available via a #define only. See the email thread.

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 :)

Fixed repr() and str() of complex numbers. Complex suffered from the same problem as floats but I forgot to test and fix them.

static PyObject* variables should use PyString_InternFromString() instead of PyObject_FromString() to store a python string in a function level static var.

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 .

Patch #1675423 : PyComplex_AsCComplex() now tries to convert an object
...
to complex using its __complex__() method before falling back to the
__float__() method. Therefore, the functions in the cmath module now
can operate on objects that define a __complex__() method.

Use sizeof(buffer) instead of duplicating the constants to ensure they won't

be wrong.
The real change is to pass (bufsz - 1) to PyOS_ascii_formatd and 1
to strncat. strncat copies n+1 bytes from src (not dest).
