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!

Constants

Single-precision floating-point mathematical constants.

Installation

npm install @stdlib/constants-float32

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md 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

var constants = require( '@stdlib/constants-float32' );

constants

Single-precision floating-point mathematical constants.

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

• ABS_MASK: mask for excluding the sign bit of a single-precision floating-point number.
• CBRT_EPS: cube root of single-precision floating-point epsilon.
• EPS: difference between one and the smallest value greater than one that can be represented as a single-precision floating-point number.
• EXPONENT_BIAS: the bias of a single-precision floating-point number's exponent.
• EXPONENT_MASK: mask for the exponent of a single-precision floating-point number.
• MAX_SAFE_INTEGER: maximum safe single-precision floating-point integer.
• MAX: maximum single-precision floating-point number.
• MIN_SAFE_INTEGER: minimum safe single-precision floating-point integer.
• NAN: single-precision floating-point NaN.
• NINF: single-precision floating-point negative infinity.
• NUM_BYTES: size (in bytes) of a single-precision floating-point number.
• PINF: single-precision floating-point positive infinity.
• PRECISION: effective number of bits in the significand of a single-precision floating-point number.
• SIGN_MASK: mask for the sign bit of a single-precision floating-point number.
• SIGNIFICAND_MASK: mask for the significand of a single-precision floating-point number.
• SMALLEST_NORMAL: smallest positive normalized single-precision floating-point number.
• SMALLEST_SUBNORMAL: smallest positive denormalized single-precision floating-point number.
• SQRT_EPS: square root of single-precision floating-point epsilon.

Examples

var objectKeys = require( '@stdlib/utils-keys' );
var constants = require( '@stdlib/constants-float32' );

console.log( objectKeys( constants ) );
