Dath

Dath stands for Degree math.

This is a simple library that adds degree variants of all trigonometric functions in the Math global variable.

npm i dmath

To use, just load dmath.js it in your app, and you will have all the extended functions in the Math global or in the DMath global. If using a module bundler or Node.JS, you will not recieve global variables but rather the DMath object in it's exports.

Alongside the degree trig functions, there are also two functions to convert between degrees and radians:

• deg2rad(x)
• rad2deg(x)

Examples

Globals, In an HTML file

<script src="https://unpkg.com/math"></script>
<script>
  console.log(Math.dcos(180));
  // or
  console.log(Dath.dcos(180));
</script>

Using Node.JS

const Math = require('math');

console.log(Math.dsin(180));

Using Webpack

import * as Math from 'math';

console.log(Math.deg2rad(60));

Why "Dath"

Originally this was called "DMath", but that was taken by d-math so i needed a new name.
