Mark Dickinson 95bc980d9e 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')

Eric Smith aca19e6a74 Backport of some of the work in r71665 to trunk. This reworks much of
int, long, and float __format__(), and it keeps their implementation
in sync with py3k.

Also added PyOS_double_to_string. This is the "fallback" version
that's also available in trunk, and should be kept in sync with that
code. I'll add an issue to document PyOS_double_to_string in the C
API.

There are many internal cleanups. Externally visible changes include:

- Implement PEP 378, Format Specifier for Thousands Separator, for
  floats, ints, and longs.

- Issue #5515: 'n' formatting for ints, longs, and floats handles
  leading zero formatting poorly.

- Issue #5772: For float.__format__, don't add a trailing ".0" if
  we're using no type code and we have an exponent.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

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.

Eric Smith cf537ff39e Addresses issue 2802: 'n' formatting for integers.
Adds 'n' as a format specifier for integers, to mirror the same
specifier which is already available for floats.  'n' is the same as
'd', but inserts the current locale-specific thousands grouping.

I added this as a stringlib function, but it's only used by str type,
not unicode.  This is because of an implementation detail in
unicode.format(), which does its own str->unicode conversion.  But the
unicode version will be needed in 3.0, and it may be needed by other
code eventually in 2.6 (maybe decimal?), so I left it as a stringlib
implementation.  As long as the unicode version isn't instantiated,
there's no overhead for this.

Eric Smith 0a95063d73 Issue 2526, float.__format__ 'n' specifier does not support thousands grouping.
Implemented grouping, with tests.
Cleaned up PyOS_ascii_formatd by breaking reformatting into smaller functions.

Eric Smith 8113ca63b9 Issue 2264: empty float presentation type needs to have at least one digit past the decimal point.
Added "Z" format_char to PyOS_ascii_formatd to support empty float presentation type.
Renamed buf_size in PyOS_ascii_formatd to more accurately reflect it's meaning.
Modified format.__float__ to use the new "Z" format as the default.
Added test cases.

Eric Smith 7ef40bf9c7 Trim leading zeros from a floating point exponent, per C99. See issue 1600. As far as I know, this only affects Windows. Add float type 'n' to PyOS_ascii_formatd (see PEP 3101 for 'n' description). 2008-02-20 23:34:22 +00:00
