[issue10650] decimal.py: quantize(): excess digits with watchexp=0

[Stefan Krah]

Stefan Krah <stefan-usenet at bytereef.org> added the comment:

NaNs, however, are decapitated:

>>> x = Decimal("NaN5357671565858315212612021522416387828577")
>>> y = 0
>>> x.quantize(y, watchexp=0)
Decimal('NaN8315212612021522416387828577')
