Big Num
This crate provides:
BigInt: Immutable arbitrary-precision integers. All operations behave as if BigInt were represented in two's-complement notation.BigDec: Immutable, arbitrary-precision signed decimal numbers. A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale. (Coming Soon)
Example
use BigInt;
let a: BigInt = "10000000000000".into;
let b: BigInt = "900000000000".into;
