One of the most, if not THE most, beautiful formulas in math, is from Euler:

It combines in it a relation between the number **e**, the number **Pi** and the complex number **i**, plus the basic math symbols 1, +, = and zero. Is that not amazing?

More info on this formula can be found here.

The Complex type in C# is available as of .NET v4.0 and lives in the System.Numerics namespace.

As this type is not used on a regular basis it is not included as reference in every project by default.

So you have to include that reference first. Don't forget to add `using System.Numerics;`

to your .cs file either.

Enjoy!
