## Usage
|
|
|
|
```javascript
|
|
var convertArraySame = require( '@stdlib/array/convert-same' );
|
|
```
|
|
|
|
#### convertArraySame( x, y )
|
|
|
|
Converts an `array` to the same data type as a second input `array`.
|
|
|
|
```javascript
|
|
var Float32Array = require( '@stdlib/array/float32' );
|
|
|
|
var y = new Float32Array( 0 );
|
|
|
|
var x = [ 1.0, 2.0, 3.0 ];
|
|
var out = convertArraySame( x, y );
|
|
// returns <Float32Array>[ 1.0, 2.0, 3.0 ]
|
|
```
|
|
|
|
The function supports input arrays having 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.
