Rounding package:HasBigDecimal

A RoundingAdvice is interpreted by divisions and rounding operations to specify the expected loss of precision and the rounding behaviour. RoundingAdvice is a pair of a RoundingMode and a target precision of type Maybe Natural. The precision defines the number of digits after the decimal point. If Nothing is given as precision all decimal digits are to be preserved, that is precision is not limited.

RoundingMode defines how to handle loss of precision in divisions or explicit rounding.
