    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/string-num2words
```

</section>

<section class="usage">

## Usage

```javascript
var num2words = require( '@stdlib/string-num2words' );
```

#### num2words( value\[, options] )

Converts a number to a word representation.

```javascript
var out = num2words( 87 );
// returns 'eighty-seven'

out = num2words( 23101 );
// returns 'twenty-three thousand one hundred one'

out = num2words( 0.53 );
// returns 'zero point five three'
```

The function accepts the following `options`:

-   **lang**: `string` indicating the language. Default: `'en'`.

By default, the function returns a word representation of a number in English. To return a word representation of a number in a different language, set the `lang` option.

```javascript
var out = num2words( 22, {
    'lang': 'de'
});
// returns 'zweiundzwanzig'

out = num2words( 0.53, {
    'lang': 'de'
});
// returns 'null Komma fünf drei'
```
