# isComplex128Array
> Test if a value is a [Complex128Array][@stdlib/array/complex128].
## Usage
```javascript
var isComplex128Array = require( '@stdlib/assert/is-complex128array' );
```
#### isComplex128Array( value )
Tests if a value is a [`Complex128Array`][@stdlib/array/complex128].
```javascript
var Complex128Array = require( '@stdlib/array/complex128' );
var bool = isComplex128Array( new Complex128Array( 10 ) );
// returns true
bool = isComplex128Array( [] );
// returns false
```
## Examples
```javascript
var Int8Array = require( '@stdlib/array/int8' );
var Uint8Array = require( '@stdlib/array/uint8' );
var Uint8ClampedArray = require( '@stdlib/array/uint8c' );
var Int16Array = require( '@stdlib/array/int16' );
var Uint16Array = require( '@stdlib/array/uint16' );
var Int32Array = require( '@stdlib/array/int32' );
var Uint32Array = require( '@stdlib/array/uint32' );
var Float32Array = require( '@stdlib/array/float32' );
var Float64Array = require( '@stdlib/array/float64' );
var Complex64Array = require( '@stdlib/array/complex64' );
var Complex128Array = require( '@stdlib/array/complex128' );
var isComplex128Array = require( '@stdlib/assert/is-complex128array' );
var bool = isComplex128Array( new Complex128Array( 10 ) );
// returns true
bool = isComplex128Array( new Complex64Array( 10 ) );
// returns false
bool = isComplex128Array( new Float64Array( 10 ) );
// returns false
bool = isComplex128Array( new Int8Array( 10 ) );
// returns false
bool = isComplex128Array( new Uint8Array( 10 ) );
// returns false
bool = isComplex128Array( new Uint8ClampedArray( 10 ) );
// returns false
bool = isComplex128Array( new Int16Array( 10 ) );
// returns false
bool = isComplex128Array( new Uint16Array( 10 ) );
// returns false

// returns false
