What data type to use for a very large numbers

Question

I'm trying to get a very big number, it doesn't work with usual integer,long... I've searched it and I found that there is a namespace named System.Numerics but when I write: Imports System.Numerics , it doesn't accept. If I could use that, I'm sure that I could also use:

Dim x as new BigInteger(y)

What can I do in this situation, are there any other methods?

You have to add a reference to System.Numerics in the solution explorer
