## Usage
```javascript
var zeros = require( '@stdlib/array/zeros' );
```
#### zeros( length\[, dtype] )
Creates a zero-filled array having a specified length.
```javascript
var arr = zeros( 2 );
// returns <Float64Array>[ 0.0, 0.0 ]
```
The function recognizes the following data types:
- `float64`: double-precision floating-point numbers (IEEE 754)
- `float32`: single-precision floating-point numbers (IEEE 754)
- `complex128`: double-precision complex floating-point numbers
- `complex64`: single-precision complex floating-point numbers
- `int32`: 32-bit two's complement signed integers
- `uint32`: 32-bit unsigned integers
- `int16`: 16-bit two's complement signed integers
- `uint16`: 16-bit unsigned integers
- `int8`: 8-bit two's complement signed integers
- `uint8`: 8-bit unsigned integers
- `uint8c`: 8-bit unsigned integers clamped to `0-255`
- `generic`: generic JavaScript values
By default, the output array data type is `float64` (i.e., a [typed array][mdn-typed-array]). To specify an alternative data type, provide a `dtype` argument.
```javascript
var arr = zeros( 2, 'int32' );
// returns <Int32Array>[ 0, 0 ]
```

```javascript
var dtypes = require( '@stdlib/array/dtypes' );
var zeros = require( '@stdlib/array/zeros' );
// Get a list of array data types:
var dt = dtypes();
// Generate zero-filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
arr = zeros( 4, dt[ i ] );
console.log( arr );
}
