Package Exports

compute-isnumeric

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-isnumeric) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isnumeric

Computes for each array element whether an element is numeric.

Installation

$ npm install compute-isnumeric

For use in the browser, use browserify.

Usage

To use the module,

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

isnumeric( arr )

Computes for each array element whether an element is numeric. The function returns an array with length equal to that of the input array. Each output array element is either 0 or 1. A value of 1 means that an element is numeric and 0 means that an element is not numeric.

var out = isnumeric( [ 5, 1/0, 'beep', 3, 9, NaN, true ] );
// returns [ 1, 1, 0, 1, 1, 0, 0 ]

Examples

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

// Simulate some data...
var data = new Array( 100 ),
    len = data.length,
    rand;

// Every so often include a non-numeric value...
for ( var i = 0; i < len; i++ ) {
    rand = Math.random()*10;
    if ( rand < 0.5 ) {
        rand = null;
    }
    data[ i ] = rand;
}

var out = isnumeric( data );

// Count the number of numeric values detected...
var sum = 0;
for ( var i = 0; i < len; i++ ) {
    sum += out[ i ];
}

console.log( 'Count: %d', sum );

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,
