No, that's decimal.Decimal and floats being an approximation:
>>> from decimal import Decimal
>>> print('{:.48f}'.format(23.45))
>>> print('{:.55f}'.format(23.45))
So decimal.Decimal's constructor converts strings to decimal numbers with as
much
precision as given. It also applies to floats, except that floats have more
precision then
typed.
