    hypot

    NPM version Build Status Coverage Status Dependencies

    Computes the square root of a sum of squares.

    The square root of a sum of squares is defined as

    hypot equation definition.

    Installation

    $ npm install math-hypot

    Usage

    var hypot = require( 'math-hypot' );

    hypot( a, b )

    Computes the square root of a sum of squares.

    var h = hypot( -5, 12 );
    // returns 13

    When a and b are both positive numbers, the result can be interpreted as the hypotenuse of a right triangle.

    var h = hypot( 5, 12 );
    // returns 13

    Examples

    var hypot = require( 'math-hypot' );
     
    var a;
    var b;
    var i;
     
    for ( i = 0; i < 100; i++ ) {
        a = Math.round( Math.random()*100 );
        b = Math.round( Math.random()*100 );
        console.log( '%d, %d, %d', a, b, hypot( a, b ) );
    }

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

    $ node ./examples/index.js

    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
