Decimal floating point arithmetic. The focus of this module is the Decimal type which performs computations using decimal floating point arithmetic. An of Decimal may be obtained by calling decimalNumber or parseDecimal.

A Rounding is used to specify how results of calculations should be rounded, and an instance may be obtained by calling round. The implicitRounding function may be used to associate a Rounding with a computation, performing the whole computation with an implicit rounding strategy.
