    Finite

    NPM version Build Status Coverage Status Dependencies

    Validates if a value is a finite number.

    Installation

    $ npm install validate.io-finite

    For use in the browser, use browserify.

    Usage

    var isFiniteNumber = require( 'validate.io-finite' );

    isFiniteNumber( value )

    Validates if a value is a finite number.

    var value = Number.MAX_VALUE;
     
    var bool = isFiniteNumber( value );
    // returns true

    Note: this method differs from the global method isFinite() in that the global method will validate non-numeric values. For any non-numeric value, this method returns false.

    Examples

    var isFiniteNumber = require( 'validate.io-finite' );
     
    console.log( isFiniteNumber( Number.MAX_VALUE ) );
    // returns true
     
    console.log( isFiniteNumber( Number.POSITIVE_INFINITY ) );
    // returns false
     
    console.log( isFiniteNumber( NaN ) );
    // returns false
     
    console.log( isFiniteNumber( '5' ) );
    // returns false

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

    $ node ./examples/index.js

    Tests

    Unit

    Unit tests use the Mocha test framework with Chai assertions. 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
