    Float

    NPM version Build Status Coverage Status Dependencies

    Validates if a value is a float.

    Installation

    $ npm install validate.io-float

    For use in the browser, use browserify.

    Usage

    var isFloat = require( 'validate.io-float' );

    isFloat( value )

    Validates if a value is a float.

    var value = Math.PI;
     
    var bool = isFloat( value );
    // returns true

    Notes

    • This method first validates that a value is a number prior to validating if the value is a float.

    • In JavaScript, every numeric value is stored as a float. Here, we make a distinction based on whether the value has digits located after a decimal point. Hence, the distinction is semantic and not indicative of the underlying representation.

    Examples

    console.log( isFloat( 5.256 ) );
    // returns true
     
    console.log( isFloat( 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
