const-eps-float32

EPSILON

Difference between one and the smallest value greater than one that can be represented as a single-precision floating-point number.

Epsilon is defined as

where b is the radix (base) and p is the precision (number of radix bits in the significand). For single-precision floating-point numbers, b is 2 and p is 24.

Installation

$ npm install const-eps-float32

Usage

var FLOAT32_EPSILON = require( 'const-eps-float32' );

FLOAT32_EPSILON

Difference between one and the smallest value greater than one that can be represented as a single-precision floating-point number.

FLOAT32_EPSILON === 1.1920928955078125e-7;

Examples

var FLOAT32_EPSILON = require( 'const-eps-float32' );
 
console.log( FLOAT32_EPSILON );
// returns 1.1920928955078125e-7

Tests

Unit

This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov

Browser Support

This repository uses Testling for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:

$ make test-browsers

To view the tests in a local web browser,

$ make view-browser-tests
