Provides classes for performing arbitrary-precision integer
arithmetic (BigInteger
) and arbitrary-precision decimal
arithmetic (BigDecimal
). BigInteger
is analogous
to the primitive integer types except that it provides arbitrary
precision, hence operations on BigInteger
s 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
rounding modes.
Classes
BigDecimal |
Immutable, arbitrary-precision signed decimal numbers. |
BigInteger |
Immutable arbitrary-precision integers. |
MathContext |
Immutable objects which encapsulate the context settings which
describe certain rules for numerical operators, such as those
implemented by the BigDecimal class. |
Enums
RoundingMode |
Specifies a rounding behavior for numerical operations
capable of discarding precision. |
