> Smallest positive [double-precision floating-point number][ieee754].

Installation

`` bash
$ npm install const-smallest-float64
`

Usage

` javascript
var SMALLEST_FLOAT64 = require( 'const-smallest-float64' );
`

#### SMALLEST_FLOAT64

An object comprised as follows:

` javascript
{
'VALUE': 2.2250738585072014e-308,
'DENORMALIZED': ~4.94e-324
}
`


##### Value

Smallest positive __normalized__ [double-precision floating-point number][ieee754].

` javascript
SMALLEST_FLOAT64.VALUE === Math.pow( 2, -(1023-1) );
`


##### Denormalized

Smallest positive __denormalized__ [double-precision floating-point number][ieee754].

` javascript
SMALLEST_FLOAT64.DENORMALIZED === Math.pow( 2, -(1023-1+52) );
`

Examples

` javascript
var SMALLEST_FLOAT64 = require( 'const-smallest-float64' );

console.log( SMALLEST_FLOAT64.VALUE );
// returns 2.2250738585072014e-308

console.log( SMALLEST_FLOAT64.DENORMALIZED );
// returns ~4.94e-324
`

Tests

$3

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

` bash
$ make test
`

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

$3

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

` bash
$ make test-cov
`

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

` bash
$ make view-cov
`

$3

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

` bash
$ make test-browsers
`

To view the tests in a local web browser,

` bash
$ make view-browser-tests
