Immutable arbitrary-precision integers.

Type	Field	Summary
static BigInteger	ONE	The BigInteger constant one.
static BigInteger	TEN	The BigInteger constant ten.
static BigInteger	ZERO	The BigInteger constant zero.

Constructor	Summary
BigInteger(byte[] val)	Translates a byte array containing the two's-complement binary representation of a BigInteger into a BigInteger.
BigInteger(int signum, byte[] magnitude)	Translates the sign-magnitude representation of a BigInteger into a BigInteger.
BigInteger(int bitLength, int certainty, Random rnd)	Creates a randomly generated positive BigInteger that is probably prime, with the specified bitLength.
BigInteger(int numBits, Random rnd)	Creates a randomly generated BigInteger, uniformly distributed over the range 0 to (2numBits - 1), inclusive.
BigInteger(String val)	Translates the decimal String representation of a BigInteger into a BigInteger.
BigInteger(String val, int radix)	Translates the String representation of a BigInteger in the specified radix into a BigInteger.

Return	Method	Summary
