The :mod:`decimal` module offers a :class:`Decimal` datatype for decimal
floating point arithmetic. Compared to the built-in :class:`float`
-implementation of binary floating point, the new class is especially helpful for

For example, calculating a 5% tax on a 70 cent phone charge gives different
results in decimal floating point and binary floating point. The difference
