From the developer:
Complex Calculator Precision 18 is a complex number calculator and works with complex numbers, but also can be used as a real number calculator, that is a scientific calculator. The calculator has backward compatibility with College Scientific Calculator series and Scientific Calculator Precision 54. Any formula which works in College Scientific Calculator will work in this calculator. For that some buttons are duplicated.
