Immutable arbitrary-precision integers. All operations behave as if
BigIntegers were represented in two's-complement notation (like Java's
primitive integer types). BigInteger 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
