Creates and initializes a BigInt.

fn parse_bytes(buf: &[u8], radix: uint) -> Option<BigInt>

Creates and initializes a BigInt.

fn to_biguint(&self) -> Option<BigUint>

Converts this BigInt into a BigUint, if it's not negative.

fn checked_add(&self, v: &BigInt) -> Option<BigInt>

fn checked_sub(&self, v: &BigInt) -> Option<BigInt>

fn checked_mul(&self, v: &BigInt) -> Option<BigInt>
