    $ npm install math-exp

    Usage

    var exp = require( 'math-exp' );

    exp( x )

    Evaluates the natural exponential function.

    var val = exp( 4 );
    // returns ~54.5982
     
    val = exp( -9 );
    // returns ~1.234e-4
     
    val = exp( 0 );
    // returns 1
     
    val = exp( NaN );
    // returns NaN

    Examples

    var exp = require( 'math-exp' );
     
    var x;
    var i;
     
    for ( i = 0; i < 100; i++ ) {
        x = Math.random()*100 - 50;
        console.log( 'e^%d = %d', x, exp( x ) );
    }

    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
