    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>

<section class="installation">

## Installation

```bash
npm install @stdlib/number-uint32-base-mul
```

</section>

<section class="usage">

## Usage

```javascript
var mul = require( '@stdlib/number-uint32-base-mul' );
```

#### mul( x, y )

Multiplies two unsigned 32-bit integers.

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

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

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   The function performs C-like multiplication of two unsigned 32-bit integers, including wraparound semantics.

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var mul = require( '@stdlib/number-uint32-base-mul' );

var opts = {
    'dtype': 'uint32'
};

// Create arrays of random values:
var x = discreteUniform( 100, 0, 50, opts );
var y = discreteUniform( 100, 0, 50, opts );

// Perform element-wise multiplication:
logEachMap( '%d * %d = %d', x, y, mul );

### Usage

```c
#include "stdlib/number/uint32/base/mul.h"
```

#### stdlib_base_uint32_mul( x, y )

Multiplies two unsigned 32-bit integers.

```c
#include <stdint.h>

uint32_t v = stdlib_base_uint32_mul( 5, 2 );
// returns 10
```

The function accepts the following arguments:

-   **x**: `[in] uint32_t` first input value.
-   **y**: `[in] uint32_t` second input value.

```c
uint32_t stdlib_base_uint32_mul( const uint32_t x, const uint32_t y );
