    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>

## Usage

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

#### mulf( x, y )

Multiplies two single-precision floating-point numbers.

```javascript
var v = mulf( -1.0, 5.0 );
// returns -5.0

v = mulf( 2.0, 5.0 );
// returns 10.0

v = mulf( 0.0, 5.0 );
// returns 0.0

v = mulf( -0.0, 0.0 );
// returns -0.0

v = mulf( NaN, NaN );
// returns NaN

### Usage

```c
#include "stdlib/math/base/ops/mulf.h"
```

#### stdlib_base_mulf( x, y )

Multiplies two single-precision floating-point numbers.

```c
float v = stdlib_base_mulf( -5.0f, 2.0f );
// returns -10.0f
```

The function accepts the following arguments:

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

```c
float stdlib_base_mulf( const float x, const float y );
