`` bash`
$ npm install compute-isinteger
For use in the browser, use browserify.
To use the module,
` javascript`
var isinteger = require( 'compute-isinteger' );
#### isinteger( arr )
Computes for each array element whether an element is an integer. 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 an integer and 0 means that an element is __not__ an integer.
` javascript`
var out = isinteger( [ 5, 3.14, 3, -9, 1/0, NaN, 0, null ] );
// returns [ 1, 0, 1, 1, 0, 0, 1, 0 ]
` javascript
var isinteger = require( 'compute-isinteger' );
// Simulate some data...
var data = new Array( 100 ),
len = data.length,
rand;
for ( var i = 0; i < len; i++ ) {
rand = Math.round( Math.random()*100 );
if ( rand < 5 ) {
rand += Number.EPSILON;
}
data[ i ] = rand;
}
var out = isinteger( data );
// Count the number of integer 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,
` bash`
$ node ./examples/index.js
Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
` bash`
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
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:
` bash`
$ make test-cov
Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,
` bash``
$ make view-cov
