    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>

> Create a [single-precision floating-point number][ieee754] from an unsigned integer corresponding to an [IEEE 754][ieee754] binary representation.

<section class="installation">

## Installation

```bash
npm install @stdlib/number-float32-base-from-word
```

</section>

<section class="usage">

## Usage

```javascript
var fromWordf = require( '@stdlib/number-float32-base-from-word' );
```

#### fromWordf( word )

Creates a [single-precision floating-point number][ieee754] from an unsigned `integer` corresponding to an [IEEE 754][ieee754] binary representation.

```javascript
var word = 1068180177; // => 0 01111111 01010110010001011010001

var f32 = fromWordf( word ); // when printed, implicitly promoted to float64
// returns 1.3370000123977661
```

## Examples

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

```javascript
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var MAX_UINT32 = require( '@stdlib/constants-uint32-max' );

### Usage

```c
#include "stdlib/number/float32/base/from_word.h"
```

#### stdlib_base_float32_from_word( word, \*x )

Creates a [single-precision floating-point number][ieee754] from an unsigned 32-bit integer corresponding to an [IEEE 754][ieee754] binary representation.

```c
#include <stdint.h>

uint32_t word = 1078523331;

float x;
stdlib_base_float32_from_word( word, &x );
```

The function accepts the following arguments:

-   **word**: `[in] uint32_t` input word.
-   **x**: `[out] float*` destination for a single-precision floating-point number.

```c
void stdlib_base_float32_from_word( const uint32_t word, float *x );
```
