                    Complex numbers
                    Imaginary unit
                    The real part of a complex number.
                    The imaginary part of a complex number, which is a real number.
                    The modulus of a complex number.
                    The argument of a complex number, in the range (-π,+π].
                    This converts a complex number from binomial form to polar form and the other way around(!). The polar form is a list formatted as {norm, argument}.
                    This is the conjugate of a complex number. Shift the sign of the imaginary part.
