ibig-rs

Big integer library.

The library implements arbitrarily large integer arithmetic in pure Rust.

The two integer types are UBig (for unsigned integers) and IBig (for signed integers).

Create numbers using the ubig and ibig macros

use ibig::{ibig, ubig};
let a = ubig!(0x10ff);
let b = ibig!(-abcd base 32);

Parsing and formatting in any base 2-36 is supported.

let a = UBig::from_str_radix("10ff", 16)?;
assert_eq!(format!("{:=^10X}", a), "===10FF===");
assert_eq!(format!("{}", a.in_radix(4)), "1003333");

Arithmetic operations will soon arrive.
