Platform RI: This utility class simplifies implementing MonetaryAmount, by providing the common functionality. The different explicitly typed methods are all reduced to methods using BigDecimal as input, hereby performing any conversion to BigDecimal as needed. Obviously this takes some time, so implementors that want to avoid this overhead should implement MonetaryAmount directly.
