PHP's atan2 in TypeScript

How to use

Install via yarn add locutus and import: import { atan2 } from 'locutus/php/math/atan2'.

Or with CommonJS: const { atan2 } = require('locutus/php/math/atan2')

Use a bundler that supports tree-shaking so you only ship the functions you actually use. Vite, webpack, Rollup, and Parcel all handle this. For server-side use this is less of a concern.

Examples

These examples are extracted from test cases that automatically verify our functions against their native counterparts.

#	code	expected result
1	atan2(1, 1)	0.7853981633974483

  //       example 1: atan2(1, 1)
  //       returns 1: 0.7853981633974483

  return Math.atan2(y, x)
}

  return Math.atan2(y, x)
}

Improve this function

Locutus is a community effort following The McDonald's Theory: we ship first iterations, hoping others will improve them. If you see something that could be better, we'd love your contribution.
