    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-nanmin
```

</section>

<section class="usage">

## Usage

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

#### nanmin( x, y )

Returns the minimum value.

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

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

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

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

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

If both arguments are `NaN`, the function returns `NaN`.

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

### Usage

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

#### stdlib_base_nanmin( x, y )

Returns the minimum value, ignoring NaN.

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

out = stdlib_base_nanmin( 4.14, 0.0 / 0.0 );
// returns 4.14
```

The function accepts the following arguments:

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

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