Is there a 128 or 256 bit double class in .net?

Question

I have an application that I want to be able to use large numbers and very precise numbers. For this, I needed a precision interpretation and IntX only works for integers.

Is there a class in .net framework or even third party(preferably free) that would do this?

Is there another way to do this?

Answer 1

Maybe the Decimal type would work for you?
