Crate yali

yali

Yali is a library for representing, and doing arithmetic with, large numbers.

Warnings

1. This library only supports positive integers.
2. This isn’t the most efficient library. This is just one of my small side projects.

Examples

Parse hex value from string:

use yali::Number;

let num_hex = "ab32fa1689fbc2c2631d4343bad3ab2155d";
let num: Number<16> = num_hex.parse().unwrap();

Regular exponentiation

use yali::Number;

let a = Number::<16>::from(2u64);
let b = Number::<16>::from(4u64);
let c = a ^ b;
assert_eq!(c, Number::<16>::from(16u64));

Modular exponentiation

use yali::Number;

let a: Number<16> = "ab32fa1689fbc2c2631d4343bad3ab2155d".parse().unwrap();
let b: Number<16> = "10001".parse().unwrap();
let n: Number<16> = "4343bad3ab2155d89fbc28c2631d".parse().unwrap();
let num = a.mod_exponentiation(b, n);

Structs

Number

A number that automatically allocates extra memory when it needs to, which means it can be as large as you want
