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!

Installation

npm install @stdlib/constants

Usage

var constants = require( '@stdlib/constants' );
constants

Namespace containing constants.

var ns = constants;
// returns {...}

Constants are split across the the following sub-namespaces:

  • array: array constants.
  • complex128: 128-bit complex number mathematical constant.
  • complex64: half-precision floating-point mathematical constants.
  • float16: half-precision floating-point mathematical constants.
  • float32: single-precision floating-point mathematical constants.
  • float64: double-precision floating-point mathematical constants.
  • int16: 16-bit signed integer mathematical constants.
  • int32: 32-bit signed integer mathematical constants.
  • int8: 8-bit signed integer mathematical constants.
  • path: path constants.
  • time: time constants.
  • uint16: 16-bit unsigned integer mathematical constants.
  • uint32: 32-bit unsigned integer mathematical constants.
  • uint8: 8-bit unsigned integer mathematical constants.
  • unicode: unicode constants.

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var constants = require( '@stdlib/constants' );

var out = constants.float64.PI;
// returns ~3.142

out = constants.array.MAX_ARRAY_LENGTH;
// returns 4294967295

out = constants.time.HOURS_IN_DAY;
// returns 24

Notice

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.
