    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-special-maxabsf
```

</section>

<section class="usage">

## Usage

```javascript
var maxabsf = require( '@stdlib/math-base-special-maxabsf' );
```

#### maxabsf( x, y )

Returns the maximum absolute single-precision floating-point number.

```javascript
var v = maxabsf( -4.0, 3.0 );
// returns 4.0

v = maxabsf( +0.0, -0.0 );
// returns +0.0
```

If any argument is `NaN`, the function returns `NaN`.

```javascript
var v = maxabsf( 4.2, NaN );
// returns NaN

v = maxabsf( NaN, 3.14 );
// returns NaN
```

### Usage

```c
#include "stdlib/math/base/special/maxabsf.h"
```

#### stdlib_base_maxabsf( x, y )

Returns the maximum absolute single-precision floating-point number.

```c
float out = stdlib_base_maxabsf( -4.2f, 3.14f );
// returns ~4.2f

out = stdlib_base_maxabsf( 0.0f, -0.0f );
// returns +0.0f
```

The function accepts the following arguments:

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

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