Package Exports

compute-sqrt

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (compute-sqrt) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Square Root

Computes an element-wise square root for each element in a numeric array.

Installation

$ npm install compute-sqrt

For use in the browser, use browserify.

Usage

To use the module,

var sqrt = require( 'compute-sqrt' );

sqrt( arr )

Computes an element-wise square root for each element in a numeric array.

var data = [ 4, 9, 16 ];

sqrt( data );
// returns [ 2, 3, 4 ]

Examples

var sqrt = require( 'compute-sqrt' );

// Simulate some data...
var data = new Array( 100 );

for ( var i = 0; i < data.length; i++ ) {
    data[ i ] = Math.round( Math.random()*1000 );
}

sqrt( data );

console.log( data.join( '\n' ) );

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

$ node ./examples/index.js

Notes

This function mutates the input array. If mutation is undesired,

var data = [ 1, 2, 3, 4 ],
    copy = data.slice();

sqrt( copy );

This function expects positive real values. For any array elements which are negative valued, the function returns NaN.

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
