## Usage

```javascript
var parseComplex64 = require( '@stdlib/complex/parse-float32' );
```

#### parseComplex64( str )

Parse a string representation of a 64-bit [complex number][@stdlib/complex/float32].

```javascript
var parseComplex64 = require( '@stdlib/complex/parse-float32' );
var real = require( '@stdlib/complex/real' );
var imag = require( '@stdlib/complex/imag' );

var str = '5 + 3i';

var z = parseComplex64( str );
// returns <Complex64>

var re = real( z );
// returns 5.0

var im = imag( z );
// returns 3.0
```

For details on the string format, see [Complex64][@stdlib/complex/float32].
