    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

```

</section>

<section class="usage">

## Usage

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

#### maxf( x, y )

Returns the maximum single-precision floating-point number.

```javascript
var v = maxf( 4.2, 3.14 );
// returns ~4.2
```

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

## Notes

-   The implementation **ignores** the sign of `0`.

    ```javascript
    var v = maxf( +0.0, -0.0 );
    // returns -0.0

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

-   The implementation does **not** check for `NaN` arguments.

    ```javascript
    var v = maxf( 3.14, NaN );
    // returns NaN

    v = maxf( NaN, 3.14 );
    // returns ~3.14
    ```

<!-- C usage documentation. -->

<section class="usage">

### Usage

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

#### stdlib_base_fast_maxf( x, y )

Returns the maximum single-precision floating-point number.

```c
float out = stdlib_base_fast_maxf( 4.2f, 3.14f );
// returns 4.2f

out = stdlib_base_fast_maxf( 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_fast_maxf( const float x, const float y );
