NettetPackage java.math Description 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. NettetBigInteger provides analogues to all of Java's primitive integer operators, and all relevant methods from java.lang.Math. Additionally, BigInteger provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.
