    NPM version Build Status Coverage Status Dependencies

    Maximum safe double-precision floating-point integer.

    Installation

    $ npm install compute-const-max-safe-integer

    Usage

    var MAX_SAFE_INTEGER = require( 'compute-const-max-safe-integer' );

    MAX_SAFE_INTEGER

    The maximum safe double-precision floating-point integer.

    MAX_SAFE_INTEGER === Math.pow( 2, 53 ) - 1; // 9007199254740991

    Examples

    var round = require( 'math-round' );
    var pow = require( 'math-power' );
    var MAX_SAFE_INTEGER = require( 'compute-const-max-safe-integer' );
     
    var max;
    var x;
    var i;
     
    max = pow( 2, 55 );
    for ( i = 0; i < 100; i++ ) {
        x = round( Math.random() * max );
        if ( x > MAX_SAFE_INTEGER ) {
            console.log( 'Unsafe: %d', x );
        } else {
            console.log( 'Safe: %d', x );
        }
    }

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

    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
