Classes
BigDecimal- provides arbitrary-precision signed decimal numbers. BigDecimal gives the user control over rounding behavior throughRoundingMode.BigInteger- provides arbitrary-precision integers. Operations on BigIntegers do not overflow or lose precision. In addition to standard arithmetic operations, it provides modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and other miscellaneous operations.MathContext- encapsulate the context settings which describe certain rules for numerical operators.
Enums
RoundingMode- provides eight rounding behaviors.
