EPSILON

Difference between one and the smallest value greater than one that can be represented as a half-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 half-precision floating-point numbers, b is 2 and p is 11.

Installation

$ npm install const-eps-float16

Usage

var FLOAT16_EPSILON = require( 'const-eps-float16' );

FLOAT16_EPSILON

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

FLOAT16_EPSILON === 0.0009765625;

Examples

var FLOAT16_EPSILON = require( 'const-eps-float16' );

console.log( FLOAT16_EPSILON );
// returns 0.0009765625

To run the example code from the top-level application directory,

$ node ./examples/index.js

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
