    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-maxn
```

</section>

<section class="usage">

## Usage

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

#### maxn( \[x\[, y\[, ...args]]] )

Returns the maximum value.

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

v = maxn( +0.0, -0.0 );
// returns +0.0

v = maxn( 4.2, 3.14, -1.0, 6.8 );
// returns 6.8
```

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

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

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

If not provided any arguments, the function returns `-infinity`.

```javascript
var v = maxn();
// returns -Infinity
```

<section class="notes">

## Notes

-   When an empty set is considered a subset of the extended reals (all real numbers, including positive and negative infinity), negative infinity is the least upper bound. Similar to zero being the identity element for the sum of an empty set and to one being the identity element for the product of an empty set, negative infinity is the identity element for the maximum, and thus, the function returns `-infinity`.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var minstd = require( '@stdlib/random-base-minstd-shuffle' );
var maxn = require( '@stdlib/math-base-special-maxn' );

var x;
var y;
var v;
var i;

for ( i = 0; i < 100; i++ ) {
    x = minstd();
    y = minstd();
    v = maxn( x, y );
    console.log( 'max(%d,%d) = %d', x, y, v );
}
