BigInteger) and arbitrary-precision decimal
arithmetic (BigDecimal). 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
rounding modes.
| Modifier and Type | Class and Description |
|---|---|
| public class | BigDecimal
Immutable, arbitrary-precision signed decimal numbers. |
| public class | BigInteger
Immutable arbitrary-precision integers. |
| pack-priv class | BitSieve
A simple bit sieve used for finding prime number candidates. |
| public class | MathContext
Immutable objects which encapsulate the context settings which
describe certain rules for numerical operators, such as those
implemented by the |
| pack-priv class | MutableBigInteger
A class used to represent multiprecision integers that makes efficient use of allocated space by allowing a number to occupy only part of an array so that the arrays do not have to be reallocated as often. |
| pack-priv class | SignedMutableBigInteger
A class used to represent multiprecision integers that makes efficient use of allocated space by allowing a number to occupy only part of an array so that the arrays do not have to be reallocated as often. |
| Modifier and Type | Enum and Description |
|---|---|
| public enum | RoundingMode
Specifies a rounding policy for numerical operations capable of discarding precision. |
