1.7 The java.math Package

The java.math package is new in Java 1.1. It contains two classes that support arithmetic on arbitrarily large integers and floating-point numbers: BigInteger and BigDecimal. The BigInteger class also defines some methods for handling modular arithmetic and determining primality that are needed for cryptographic purposes. See Chapter 14, The java.math Package, for complete reference material on the two classes in this package.
