## Usage
```javascript
var convertArray = require( '@stdlib/array/convert' );
```
#### convertArray( arr, dtype )
Converts an `array` to an array of a different data type.
```javascript
var arr = [ 1.0, 2.0, 3.0 ];
var out = convertArray( arr, 'float32' );
// returns <Float32Array>[ 1.0, 2.0, 3.0 ]
```
The function supports the following data types:
- `float32`: single-precision floating-point numbers.
- `float64`: double-precision floating-point numbers.
- `generic`: values of any type.
- `int16`: signed 16-bit integers.
- `int32`: signed 32-bit integers.
- `int8`: signed 8-bit integers.
- `uint16`: unsigned 16-bit integers.
- `uint32`: unsigned 32-bit integers.
- `uint8`: unsigned 8-bit integers.
- `uint8c`: unsigned clamped 8-bit integers.

## Examples
<!-- eslint no-undef: "error" -->
```javascript
var dtypes = require( '@stdlib/array/dtypes' );
var randu = require( '@stdlib/random/base/randu' );
var floor = require( '@stdlib/math/base/special/floor' );
var convertArray = require( '@stdlib/array/convert' );
// Create a generic array:
var arr = [];
var i;
for ( i = 0; i < 5; i++ ) {
arr.push( floor( randu()*1.0e25 ) - 5.0e24 );
}
// Get a list of array data types:
var DTYPES = dtypes();
// Convert the generic array to each array data type:
var out;
for ( i = 0; i < DTYPES.length; i++ ) {
out = convertArray( arr, DTYPES[ i ] );
console.log( out );
}
