The Equality method defines the operation of the equality operator for Complex values. It enables code such as the following:

Languages that do not support custom operators can call the Equals(Complex) method instead.

Two complex numbers are equal if their real parts are equal and their imaginary parts are equal. The Equality method is equivalent to the following expression:

Note that, because of differences in precision, two complex numbers that are apparently equivalent can be considered unequal. For more information and a possible workaround, see the Equals(Complex) method.
