PHP's long2ip in TypeScript

How to use

Install via yarn add locutus and import: import { long2ip } from 'locutus/php/network/long2ip'.

Or with CommonJS: const { long2ip } = require('locutus/php/network/long2ip')

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	long2ip( 3221234342 )	'192.0.34.166'

}

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.
