Class BigIntegerAlgebra

java.math.BigInteger

BigIntegerAlgebra

All Implemented Interfaces:

Serializable, Comparable<BigInteger>

public class BigIntegerAlgebra
extends BigInteger

Wrapper for java.math.BigInteger. Required for mixed arithmetic with int or long operands because java.math.BigInteger does not implement a BigInteger(long) constructor.

Note: As class BigIntegerAlgebra extends class java.math.BigInteger methods of the later class can be called on BigIntegerAlgebra instances. The methods however will not return an BigIntegerAlgebra instance but an instance of the super class as result. If needed, call the BigIntegerAlgebra(BigInteger) constructor on the result to get a BigIntegerAlgebra instance again. If this is considered inconvenient, wrapper methods for all relevant methods of BigInteger need to be implemented in the Algebra wrapper class.
