Joda-Money

Joda-Money provides a library of classes to store amounts of money.

Joda-Money does not provide, nor is it intended to provide, monetary algorithms beyond the most basic and obvious. This is because the requirements for these algorithms vary widely between domains. This library is intended to act as the base layer, providing classes that should be in the JDK.

As a flavour of Joda-Money, here's some example code:

// create a monetary value
Money money = Money.parse("USD 23.87");

// add another amount with safe double conversion
CurrencyUnit usd = CurrencyUnit.of("USD");
money = money.plus(Money.of(usd, 12.43d));

// subtracts an amount in dollars
money = money.minusMajor(2);

// multiplies by 3.5 with rounding
money = money.multipliedBy(3.5d, RoundingMode.DOWN);

// compare two amounts
boolean bigAmount = money.isGreaterThan(dailyWage);

// convert to GBP using a supplied rate
BigDecimal conversionRate = ...;  // obtained from code outside Joda-Money
Money moneyGBP = money.convertedTo(CurrencyUnit.GBP, conversionRate, RoundingMode.HALF_EVEN);

// use a BigMoney for more complex calculations where scale matters
BigMoney moneyCalc = money.toBigMoney();

Releases

Release 1.0.1 is the current release. This release is considered stable and worthy of the 1.x tag. It depends on Java SE 8 or later.

Joda-Money does have a compile-time dependency on Joda-Convert, but this is not required at runtime thanks to the magic of annotations.
