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!
Platform byte order.
npm install @stdlib/os-byte-order
var BYTE_ORDER = require( '@stdlib/os-byte-order' );
Platform byte order.
console.log( BYTE_ORDER );
// => <string>
-
The following values are possible:
'little-endian'
'big-endian'
-
'mixed-endian'
(also known as "middle-endian") 'unknown'
var BYTE_ORDER = require( '@stdlib/os-byte-order' );
if ( BYTE_ORDER === 'little-endian' ) {
console.log( 'Least significant byte comes first...' );
} else if ( BYTE_ORDER === 'big-endian' ) {
console.log( 'Most significant byte comes first...' );
} else {
console.log( 'This is uncommon...' );
}
#include "stdlib/os/byte_order.h"
Macro for an arbitrary constant indicating little-endian order.
#if defined(STDLIB_OS_BYTE_ORDER) && STDLIB_OS_BYTE_ORDER == STDLIB_OS_ORDER_LITTLE_ENDIAN
// Do something for little-endian...
#endif
If compiled on an unrecognized/unsupported platform, the macro is not defined.
Macro for an arbitrary constant indicating big-endian order.
#if defined(STDLIB_OS_BYTE_ORDER) && STDLIB_OS_BYTE_ORDER == STDLIB_OS_ORDER_BIG_ENDIAN
// Do something for big-endian...
#endif
If compiled on an unrecognized/unsupported platform, the macro is not defined.
Macro which equals either STDLIB_OS_ORDER_LITTLE_ENDIAN
or STDLIB_OS_ORDER_BIG_ENDIAN
(or host defined) depending on the resolved platform byte order.
#if defined(STDLIB_OS_BYTE_ORDER)
#if STDLIB_OS_BYTE_ORDER == STDLIB_OS_ORDER_LITTLE_ENDIAN
// Do something for little-endian...
#elif STDLIB_OS_BYTE_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.

@stdlib/os-byte-order-cli
: CLI package for use as a command-line utility. -
@stdlib/assert-is-big-endian
: check if an environment is big endian. -
@stdlib/assert-is-little-endian
: check if an environment is little endian.
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
