The bit is a basic unit of information in information theory, computing. This package includes bit twiddling hacks by Sean Eron Anderson and many others. :package: NPM, :smiley_cat: GitHub, :running: RunKit, :vhs: Asciinema, :moon: Minified, :scroll: Files, :newspaper: JSDoc, :blue_book: Wiki.

Stability: Experimental.

This is browserified, minified version of extra-bit. It is exported as global variable bit. CDN: unpkg, jsDelivr.

const bit = require("extra-bit");
// import * as bit from "extra-bit";
// import * as bit from "https://unpkg.com/[email protected]/index.mjs"; (deno)

bit.count(7);
// 3 (111 ⇒ 3)

bit.parity(8, 2);
// 2 (10,00 ⇒ 10)

bit.swap(6, 1, 0);
// 5 (110 ⇒ 101)

bit.reverse(0xFFFF0000);
// 65535 (0x0000FFFF)

bit.signExtend(15, 4);
// -1
