In this library, the numbers are represented in base B = 10**N, where N is the largest possible value that does not cause overflow in the intermediate computations. The base B elements are stored in an array, with the least significant element stored in array element zero. There are no leading zero elements, except a single zero element when the number is zero.
Alternative libraries Math::BigInt::FastCalc, Math::BigInt::GMP, and Math::BigInt::Pari.
Some of the modules that use these libraries Math::BigInt, Math::BigFloat, and Math::BigRat.
