    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Usage

```javascript
var parseComplex128 = require( '@stdlib/complex-float64-parse' );
```

#### parseComplex128( str )

Parses a string representation of a 128-bit [complex number][@stdlib/complex/float64/ctor].

```javascript
var real = require( '@stdlib/complex-float64-real' );
var imag = require( '@stdlib/complex-float64-imag' );

var str = '5 + 3i';

var z = parseComplex128( str );
// returns <Complex128>

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

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

For details on the string format, see [Complex128][@stdlib/complex/float64/ctor].

var str = '1e3 - 2.75i';

var z = parseComplex128( str );
var bool = isComplex128( z );
// returns true

bool = ( real( z ) === 1e3 );
// returns true

bool = ( imag( z ) === -2.75 );
// returns true
