Money

final class Money extends Quantity[Money]

Represents a quantity of Money.

Money is similar to other quantities in that it represents an amount of something - purchasing power - and it is measured in units - currencies.

The main difference is that the conversion rate between currencies can not be certain at compile. (In fact it may not always be so easy to know them at runtime as well.)

To address this diversion from the way most other quantities work, Money overrides several of the standard methods and operators to ensure one of two rules is followed:

1) this and that are in the same currency, or 2) there is in an implicit MoneyContext in scope (which may or may not have the applicable exchange rate)

Methods and operations applied to moneys of different currencies may throw a NoSuchExchangeRateException if the implicit MoneyContext does not contain the Rate(s) necessary to perform the conversion.

The defaultMoneyContext includes USD as the default currency, a list of ~20 other currencies and NO exchange rates
