 You will have to implement your own equality operator for the `ComplexNumber` object.
 This will pose the challenge of comparing two floating point numbers.
 It might be useful to use the method `isApproximatelyEqual(to:absoluteTolerance:)` which can be found in the [Numerics][swift-numberics] library.
+Due to preformance issues will you only have access to the `RealModule` part.
+To import it simply write: `import RealModule` at the top of the file.
 A given tolerance of `0.00001` should be enough to pass the tests.
 The library is already imported in the project so it is just to import it in your file.
