    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-minmax
```

</section>

<section class="usage">

## Usage

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

#### minmax( x, y )

Returns the minimum and maximum values in a single pass.

```javascript
var v = minmax( 4.2, 3.14 );
// returns [ 3.14, 4.2 ]

v = minmax( +0.0, -0.0 );
// returns [ -0.0, +0.0 ]
```

If any argument is `NaN`, the function returns `NaN` for both the minimum value and the maximum value.

```javascript
var v = minmax( 4.2, NaN );
// returns [ NaN, NaN ]

v = minmax( NaN, 3.14 );
// returns [ NaN, NaN ]
```

#### minmax.assign( x, y, out, stride, offset )

Returns the minimum and maximum values in a single pass and assigns results to a provided output array.

```javascript
var Float64Array = require( '@stdlib/array-float64' );

var out = new Float64Array( 2 );

var v = minmax.assign( 5.0, -2.0, out, 1, 0 );
// returns <Float64Array>[ -2.0, 5.0 ]

var bool = ( v === out );
// returns true
```

### Usage

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

#### stdlib_base_minmax( x, y, &min, &max )

Evaluates the minimum and maximum values in a single pass.

```c
double x = 3.14;
double y = 2.71;

double min;
double max;
stdlib_base_minmax( x, y, &min, &max );
```

The function accepts the following arguments:

-   **x**: `[in] double` first number.
-   **y**: `[in] double` second number.
-   **min**: `[out] double` destination for the minimum value.
-   **max**: `[out] double` destination for the maximum value.

```c
void stdlib_base_minmax( const double x, const double y, double* min, double* max );
```
