    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>

```

</section>

<section class="usage">

## Usage

```javascript
var FLOAT_WORD_ORDER = require( '@stdlib/os-float-word-order' );
```

#### FLOAT_WORD_ORDER

Platform float word order.

```javascript
console.log( FLOAT_WORD_ORDER );
// => <string>
```

<!-- /.usage -->

<section class="notes">

## Notes

-   The following values are possible:

    -   `'little-endian'`
    -   `'big-endian'`
    -   `'unknown'`

## Examples

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

```javascript

### Usage

```c
#include "stdlib/os/float_word_order.h"
```

#### STDLIB_OS_FLOAT_WORD_ORDER

Macro which equals either `__FLOAT_WORD_ORDER__` (host defined) or [`STDLIB_OS_BYTE_ORDER`][@stdlib/os/byte-order].

```c
#include "stdlib/os/byte_order.h"

#if defined(STDLIB_OS_FLOAT_WORD_ORDER)

#if STDLIB_OS_FLOAT_WORD_ORDER == STDLIB_OS_ORDER_LITTLE_ENDIAN

// Do something for little-endian...

#elif STDLIB_OS_FLOAT_WORD_ORDER == STDLIB_OS_ORDER_BIG_ENDIAN

// Do something for big-endian...

#endif

#endif
```

If compiled on an unrecognized/unsupported platform, the macro is **not** defined.
