## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var reviver = require( '@stdlib/complex/reviver-float32' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### reviver( key, value )
|
||
|
|
|
||
|
|
Revives a JSON-serialized 64-bit [complex number][@stdlib/complex/float32].
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var parseJSON = require( '@stdlib/utils/parse-json' );
|
||
|
|
|
||
|
|
var str = '{"type":"Complex64","re":5,"im":3}';
|
||
|
|
|
||
|
|
var z = parseJSON( str, reviver );
|
||
|
|
// returns <Complex64>
|
||
|
|
```
|
||
|
|
|
||
|
|
