# isComplex
> Test if a value is a [64-bit][@stdlib/complex/float32] or [128-bit][@stdlib/complex/float64] complex number.
<section class="usage">
## Usage
```javascript
var isComplex = require( '@stdlib/assert/is-complex' );
```
#### isComplex( value )
Tests if a value is a [64-bit][@stdlib/complex/float32] or [128-bit][@stdlib/complex/float64] complex number.
```javascript
var Complex128 = require( '@stdlib/complex/float64' );
var Complex64 = require( '@stdlib/complex/float32' );
var x = new Complex128( 1.0, 3.0 );
var bool = isComplex( x );
// returns true
x = new Complex64( 3.0, 1.0 );
bool = isComplex( x );
// returns true
```
