bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049)
...
Add "z" format specifier to coerce negative 0 to zero.
See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995 ) for discussion.
This covers `str.format()` and f-strings. Old-style string interpolation is not supported.

The other half of Issue #1580 : use short float repr where possible.
...
Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.
Also addresses these, which are intertwined with the short repr
changes:
- Issue #5772 : format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515 : 'n' formatting with commas no longer works poorly
with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
for floats.
