EPSILON
Difference between one and the smallest value greater than one that can be represented as a double-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 double-precision floating-point numbers, b
is 2
and p
is 53
.
Installation
$ npm install const-eps-float64
Usage
var FLOAT64_EPSILON = require( 'const-eps-float64' );
FLOAT64_EPSILON
Difference between one and the smallest value greater than one that can be represented as a double-precision floating-point number.
FLOAT64_EPSILON === 2.220446049250313e-16;
Examples
var FLOAT64_EPSILON = require( 'const-eps-float64' );
console.log( FLOAT64_EPSILON );
// returns 2.220446049250313e-16

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
