    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/math-base-ops-umul
```

</section>

<section class="usage">

## Usage

```javascript
var umul = require( '@stdlib/math-base-ops-umul' );
```

#### umul( a, b )

Performs C-like multiplication of two unsigned 32-bit integers.

```javascript
var v = umul( 10>>>0, 4>>>0 );
// returns 40

v = umul( 2147483648>>>0, 5>>>0 ); // 2^31 * 5 = 10737418240 => 32-bit integer overflow
// returns 2147483648
```

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var UINT32_MAX = require( '@stdlib/constants-uint32-max' );
var umul = require( '@stdlib/math-base-ops-umul' );
