Rounding of float on format is inconsistent with CPython

Rounding when using formatting should be done towards the even choice when doing string formatting. CPython: ``` >>> str(10000000000.25) '10000000000.2' >>> str(10000000000.75) '10000000000.8' ``` IronPython: ``` >>> str(10000000000.25) '10000000000.3' >>>...

The following example using the `rstr` package fails since it tries to use `re.sre_parse` ```Python import rstr rstr.xeger(r'[A-Z]\d[A-Z] \d[A-Z]\d') ``` It appears that `re.sre_parse` is the same thing as `sre_parse`:...
