+## Usage
+
+```javascript
+var parseComplex128 = require( '@stdlib/complex/parse-float64' );
+```
+
+#### parseComplex128( str )
+
+Parses a string representation of a 128-bit [complex number][@stdlib/complex/float64].
+
+```javascript
+var real = require( '@stdlib/complex/real' );
+var imag = require( '@stdlib/complex/imag' );
+
+var str = '5 + 3j';
+
+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].
