$ npm install --save is-same-angle

Returns true if first and second argument are same angles. By default the angles must be passed in radian.

const isSameAngle = require('is-same-angle');

isSameAngle(0, 2 * Math.PI);
//=> true

// Use the options argument for degrees
isSameAngle(0, 360, {isDegree: true});
//=> true

Type: number

First angle by default it is assumed to be in radian format. See options for using other angle units.

Type: number
