A new package, java.math, was added to the JDK 1.1 release.
The math package contains two new classes: BigInteger and BigDecimal.
BigInteger numbers are immutable arbitrary-precision
integers. They provide analogs to all of Java's primitive integer
operators and all relevant static methods from the java.lang.Math
class. Additionally, BigInteger numbers provide operations
for modular arithmetic, GCD calculation, primality testing, prime
generation, single-bit manipulation, and a few other odds and ends.
BigDecimal numbers are immutable, arbitrary-precision
signed decimal numbers, suitable for monetary calculations.
BigDecimal numbers provide operations for basic
arithmetic, scale manipulation, comparison, format conversion, and
hashing.
