    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>

## Usage

```javascript

```

#### div( x, y )

Divides two double-precision floating-point numbers.

```javascript
var v = div( -1.0, 5.0 );
// returns -0.2

v = div( 2.0, 5.0 );
// returns 0.4

v = div( 0.0, 5.0 );
// returns 0.0

v = div( -0.0, 5.0 );
// returns -0.0

v = div( NaN, NaN );
// returns NaN

### Usage

```c
#include "stdlib/math/base/ops/div.h"
```

#### stdlib_base_div( x, y )

Divides two double-precision floating-point numbers.

```c
double v = stdlib_base_div( -5.0, 2.0 );
// returns -2.5
```

The function accepts the following arguments:

-   **x**: `[in] double` first input value (dividend).
-   **y**: `[in] double` second input value (divisor).

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