About stdlib…

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.

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.

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.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Float word Order

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]

Platform [float word order][endianness].

## Installation

bash
npm install @stdlib/os-float-word-order

Alternatively,

- To load the package in a website via a script tag without installation and bundlers, use the [ES Module][es-module] available on the [esm][esm-url] branch (see [README][esm-readme]).
- If you are using Deno, visit the [deno][deno-url] branch (see [README][deno-readme] for usage intructions).
- For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [umd][umd-url] branch (see [README][umd-readme]).
- To use as a general utility for the command line, install the corresponding [CLI package][cli-section] globally.

The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## 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>

## Notes

- The following values are possible:

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

## Examples

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

if ( FLOAT_WORD_ORDER === 'little-endian' ) {
    console.log( 'Least significant word comes first...' );
} else if ( FLOAT_WORD_ORDER === 'big-endian' ) {
    console.log( 'Most significant word comes first...' );
} else {
    console.log( 'This is uncommon...' );
}

## C APIs

### Usage

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

#### STDLIBOSFLOAT_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.

### Examples

c
#include "stdlib/os/float_word_order.h"
#include "stdlib/os/byte_order.h"
#include <stdio.h>

int main( void ) {
#if defined(STDLIB_OS_FLOAT_WORD_ORDER)
#if STDLIB_OS_FLOAT_WORD_ORDER == STDLIB_OS_ORDER_LITTLE_ENDIAN
    printf( "Least significant word comes first...\n" );
#elif STDLIB_OS_FLOAT_WORD_ORDER == STDLIB_OS_ORDER_BIG_ENDIAN
    printf( "Most significant word comes first...\n" );
#else
    printf( "Platform float word order is unknown...\n" )
#endif
#endif
}

## CLI

## Installation

To use as a general utility, install the CLI package globally

bash
npm install -g @stdlib/os-float-word-order-cli

### Usage

text
Usage: float-word-order [options]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.

### Examples

bash
$ float-word-order
