An easy to use calculator that divides two complex numbers.

Let w and z be two complex numbers such that w = a + ib and z = A + iB. w z = (a + ib)(A + iB) = a A + a B i + b A i + i^{2} b B = a A - b B + i(a B + b A)

How to use the calculator Enter the real and imaginary parts (as an integer, a decimal or a fraction) of two complex numbers z and w and press "enter".
