Provides classes for performing arbitrary-precision integer arithmetic (
BigInteger) and arbitrary-precision decimal
BigInteger is analogous
to the primitive integer types except that it provides arbitrary
precision, hence operations on
BigIntegers do not overflow
or lose precision. In addition to standard arithmetic operations,
BigInteger provides modular arithmetic, GCD calculation,
primality testing, prime generation, bit manipulation, and a few
other miscellaneous operations.
BigDecimal provides arbitrary-precision signed decimal
numbers suitable for currency calculations and the like.
BigDecimal gives the user complete control over rounding behavior,
allowing the user to choose from a comprehensive set of eight
ClassDescriptionImmutable, arbitrary-precision signed decimal numbers.Immutable arbitrary-precision integers.Immutable objects which encapsulate the context settings which describe certain rules for numerical operators, such as those implemented by the
BigDecimalclass.Specifies a rounding policy for numerical operations capable of discarding precision.
