The subtraction of a complex number, c + di, from another complex number, a + bi, takes the following form:

(a - c) + (b - d)i

If the method call results in an overflow in either the real or imaginary component, the value of that component is either Double.PositiveInfinity or Double.NegativeInfinity.

Languages that do not support custom operators can use the Subtract method to perform subtraction using complex numbers.
