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
financial applications and other uses which require exact decimal
representation, control over precision, control over rounding to meet legal or
regulatory requirements, tracking of significant decimal places, or for
applications where the user expects the results to match calculations done by
hand.

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
