PHP's base_convert in TypeScript

How to use

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

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

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	base_convert('A37334', 16, 2)	'101000110111001100110100'

Here's what our current TypeScript equivalent to PHP's base_convert looks like.

  return parseInt(number + '', frombase | 0).toString(tobase | 0)
}

}

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.
