PHP's hexdec in TypeScript

How to use

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

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

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	hexdec('that')	10
2	hexdec('a0')	160

Copy code

export function hexdec(hexString: string): number {
  //      discuss at: https://locutus.io/php/hexdec/
  // parity verified: PHP 8.3
  //     original by: Philippe Baumann
  //       example 1: hexdec('that')
  //       returns 1: 10
  //       example 2: hexdec('a0')
  //       returns 2: 160

  hexString = (hexString + '').replace(/[^a-f0-9]/gi, '')
  return parseInt(hexString, 16)
}

export function hexdec(hexString) {
  //      discuss at: https://locutus.io/php/hexdec/

  hexString = (hexString + '').replace(/[^a-f0-9]/gi, '')
  return parseInt(hexString, 16)
}

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.
