PHP's bindec in TypeScript

How to use

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

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

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	bindec('110011')	51
2	bindec('000110011')	51
3	bindec('111')	7

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

Copy code

export function bindec(binaryString: string): number {
  //      discuss at: https://locutus.io/php/bindec/
  // parity verified: PHP 8.3
  //     original by: Philippe Baumann
  //       example 1: bindec('110011')
  //       returns 1: 51
  //       example 2: bindec('000110011')
  //       returns 2: 51
  //       example 3: bindec('111')
  //       returns 3: 7

  binaryString = (binaryString + '').replace(/[^01]/gi, '')

  return parseInt(binaryString, 2)
}

export function bindec(binaryString) {
  //      discuss at: https://locutus.io/php/bindec/

  //       returns 3: 7

  binaryString = (binaryString + '').replace(/[^01]/gi, '')

  return parseInt(binaryString, 2)
}

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.
