[issue23096] Implementation-depended pickling floats with protocol 0

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Python and C implementations of pickle produce different results when pickle floats with protocol 0.

>>> pickle.dumps(4.2, 0)
b'F4.2000000000000002\n.'
>>> pickle._dumps(4.2, 0)
b'F4.2\n.'
