## Usage
|
|
|
|
```javascript
|
|
var isComplexLike = require( '@stdlib/assert/is-complex-like' );
|
|
```
|
|
|
|
#### isComplexLike( value )
|
|
|
|
Tests if a value is a complex number-like `object`.
|
|
|
|
```javascript
|
|
var Complex128 = require( '@stdlib/complex/float64' );
|
|
var Complex64 = require( '@stdlib/complex/float32' );
|
|
|
|
var x = new Complex128( 1.0, 3.0 );
|
|
var bool = isComplexLike( x );
|
|
// returns true
|
|
|
|
x = new Complex64( 3.0, 1.0 );
|
|
bool = isComplexLike( x );
|
|
// returns true
|
|
|
|
x = {
|
|
're': 1.0,
|
|
'im': -1.0
|
|
};
|
|
bool = isComplexLike( x );
|
|
// returns true
|
|
```

## Notes
|
|
|
|
- A complex number-like `object` is defined as an `object` having the following properties assigned to numeric values:
|
|
|
|
- **re**: real component.
|
|
- **im**: imaginary component.
