# bigint-mod-arith 

Some extra functions to work with modular arithmetics using native JS (stage 3) implementation of BigInt.

## Usage examples

```javascript
const modArith = require('bigint-mod-arith');

let a = 5n;
let b = 2n;
let n = 19n;

console.log(modArith.modPow(a, b, n)); // prints 13

console.log(modArith.modInv(2n, 5n)); // prints 3

console.log(modArith.modInv(3n, 5n)); // prints 2
```
