Use of Complex Class in C#

The System.Numerics.Complex structure, which was introduced in .NET 4.0, enables us to manipulate and do arithmetic with complex numbers i.e. numbers of the form a + bi where i represents the square root of -1 and a and b are real numbers.

Note that, to use it, you need to add a reference to System.Numerics.dll to your project.
