Ummm, something like this?

The three numbers which are presented here exceed the size of integers for a 
32-bit architecture, and they are, therefore, implemented using the GMP 
library. However, the user needs not know this: you just work with integer 
numbers and ECL decides whether to manipulate them as GMP integers or not.
