\section{Decimal Floating Point Arithmetic\label{decimal-fp}}
The \module{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 hand calculations as taught in school.

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