    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="usage">

## Usage

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

#### max( x, y )

Returns the maximum value.

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

## Notes

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

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

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

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

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

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

### Usage

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

#### stdlib_base_fast_max( x, y )

Returns the maximum value.

```c
double out = stdlib_base_fast_max( 4.2, 3.14 );
// returns 4.2

out = stdlib_base_fast_max( 0.0, -0.0 );
// returns 0.0
```

The function accepts the following arguments:

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

```c
double stdlib_base_fast_max( const double x, const double y );
