[−][src]Crate ibig

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.

Macros

ibig	Create an `IBig` value.
ubig	Create a `UBig` value.

IBig	Signed big integer.
InRadix	Representation of a `UBig` or `IBig` in any radix between 2 and 36 inclusive.
OutOfBoundsError	Number out of bounds.
UBig	Unsigned big integer.

Parse error when parsing UBig or IBig.
