This version of the code includes additional methods for dividing complex numbers, converting real and imaginary numbers to complex numbers, converting complex numbers from polar form to rectangular form (real and imaginary), and vice versa, converting complex numbers from rectangular form to polar form.

The division method calculates the division between two complex numbers.

The static methods `real_to_complex` and `imaginary_to_complex` convert a real or imaginary number to a complex number with the real or imaginary part set accordingly.

The static method `from_polar` converts a complex number from polar form, where `magnitude` is the distance from the origin and `phase` is the angle from the positive real axis, to rectangular form.

The `to_polar` method converts a complex number from rectangular form to polar form, returning the magnitude and phase.

These additions provide a more comprehensive range of operations and conversions for complex numbers.
