> Casts an array to an array of a different data type.


## Installation

``` bash
$ npm install dstructs-cast-arrays
```

For use in the browser, use [browserify][browserify].


## Usage

``` javascript
var cast = require( 'dstructs-cast-arrays' );
```

#### cast( x, type )

Casts an input `array` or [`array-like`][array-like] object to a specified `array` type.

``` javascript
var arr = Int32Array( 10 );

var out = cast( arr, 'float32' );
// returns Float32Array
```

`type` may be either a `string` specifying the desired output `array` data type or a value from which the desired data type should be inferred.

``` javascript
var x = Int32Array( 10 ),
	y = Float32Array( 25 );

// Cast `x` to be the same data type as `y`:
var out = cast( x, y );
// returns Float32Array
```

For a list of supported output `array` data types, see [dstructs-array-constructors][dstructs-array-constructors].



## Examples

``` javascript
var cast = require( 'dstructs-cast-arrays' ),
	arr,
	x, y, z;

arr = new Int8Array( 10 );
x = cast( arr, 'int16' );
// returns Int16Array

arr = new Array( 100 );
y = cast( arr, 'float64' );
// returns Float64Array

z = cast( x, y );
// returns Float64Array
```

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

``` bash
$ node ./examples/index.js
```


## Tests

### Unit

Unit tests use the [Mocha][mocha] test framework with [Chai][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.


### Test Coverage

This repository uses [Istanbul][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
```
