Smallest positive single-precision floating-point number.

Installation

$ npm install compute-const-smallest-float32

Usage

var SMALLEST_FLOAT32 = require( 'compute-const-smallest-float32' );

SMALLEST_FLOAT32

An object comprised as follows...

{
    'VALUE': 1.1754943508222875e-38,
    'DENORMALIZED': 1.401298464324817e-45
}

Value

Smallest positive normalized single-precision floating-point number.

SMALLEST_FLOAT32.VALUE === 1 / Math.pow( 2, 127-1 );

Denormalized

Smallest positive denormalized single-precision floating-point number.

SMALLEST_FLOAT32.DENORMALIZED === 1 / Math.pow( 2, 127-1+23 );

Examples

var SMALLEST_FLOAT32 = require( 'compute-const-smallest-float32' );
 
console.log( SMALLEST_FLOAT32.VALUE );
// returns 1.1754943508222875e-38
 
console.log( SMALLEST_FLOAT32.DENORMALIZED );
// returns 1.401298464324817e-45

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
