Working with arbitrary numbers

I want to write a class which can handle numbers of an arbitrary length with simple commands such as DD(10000000000,10000000000) to show 20000000000

I've found a list of the limits in C# for data types:

Data type                                     Maximum positive value
Int32                                                  2,147,483,647
UInt32                                                 4,294,967,295
Int64                                      9,223,372,036,854,775,808
UInt64                                    18,446,744,073,709,551,615

But what if my number, for example, is 20,000,000,000,000,000,000,000,000

How would I do it?

You can use System.Numerics.BigInteger:

You can use System.Numerics.BigInteger

Represents an arbitrarily large signed integer.
