This will be fixed in this version for Ubuntu 16.10. I'm going to go ahead and close the 16.10 bug task now since it wasn't mentioned in the changelog.

Under these conditions the calculator exponentiates the real part of the base and leaves its imaginary part intact, that does not agree with the complex numbers operation rules. If the exponent is not a positive integer, the calculation is performed correctly. Steps to reproduce the bug: 1. Start the program. 2. Evaluate expression "i^2". The displayed result is "i". 3. Evaluate expression "(1+i)^2". The displayed result is "1+i". 4. Evaluate expression "(2+i)^2". The displayed result is "4+i". Please find a quick fix patch attached. I did not study its comprehensiveness and optimality, but it seems to work.
