[issue45995] string formatting: normalize negative zero

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

To normalize negative 0.0 to 0.0 you can just add 0.0. It will work with any method of converting floats to string, there is no need to change all formatting specifications.

>>> x = -0.0
>>> x
-0.0
>>> x + 0.0
0.0
