Pairing

Number pairing functions with support for BigInt numbers.

Features

• Simple API;
• Works with plain numbers or BigInt;
• Extensive tests;
• Typescript support.

Installation

npm install pairing

Requirements

• Node.js v.14+

Quick start

import { elegant } from 'pairing';

// encode bigint numbers
const z = elegant.encode(3037000499n, 2891526307n); // returns 9223372036854775807n

// decode bigint number
const [x, y] = elegant.decode(9223372036854775807n); // returns [3037000499n, 2891526307n]

Supported pairing functions

• Szudzik Pairing, a.k.a. Elegant

Motivation

Pairing functions are magic. They encode two natural numbers into a derivative natural. This can be useful in various use-cases, such as optimizing compound numeric indices.

At the time of writing, none of the existing libraries in npm supported BigInt calculations. Types were also missing.
