Code is very hard to read if addition is s128_add(&result, a b); and the same is true for the other four arithmetical operation.

C++ help me to test using the same template code using different types and bases. To convert to C, it's necessary to create "instances" with names add_base10_int something like that. Maybe the selection also could be done using _Generic. I would not use C++ to override operators +, - etc.. Because this could be added latter (in other code) if someone need.
