    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

```

<section class="usage">

## Usage

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

#### clampf( v, min, max )

Restricts a single-precision floating-point number to a specified range.

```javascript
var v = clampf( 3.0, 0.0, 5.0 );
// returns 3.0

v = clampf( -3.0, 0.0, 5.0 );
// returns 0.0

v = clampf( 10.0, 0.0, 5.0 );
// returns 5.0

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

v = clampf( 0.0, -3.0, -0.0 );
// returns -0.0
```

If provided `NaN` for any argument, the function returns `NaN`.

```javascript
var v = clampf( NaN, 0.0, 5.0 );
// returns NaN

v = clampf( 0.0, NaN, 5.0 );
// returns NaN

v = clampf( 3.14, 0.0, NaN );
// returns NaN

### Usage

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

#### stdlib_base_clampf( v, min, max )

Restricts a single-precision floating-point number to a specified range.

```c
float y = stdlib_base_clampf( -3.14f, 0.0f, 5.0f );
// returns 0.0f
```

The function accepts the following arguments:

-   **v**: `[in] float` input value.
-   **min**: `[in] float` minimum value.
-   **max**: `[in] float` maximum value.

```c
float stdlib_base_clampf( const float v, const float min, const float max );
```
