Currently some preprocessing steps are using type of information in order to get result.

For example, Custom multiplier used with "Numeric (unsigned)" type will give result that is casted to unsigned numeric:

Changing type of information will also change the result of preprocessing:

As for the other preprocessing types (like Javascript), result is not casted. For "Numeric (unsigned)", result of the Javascript is the following:

I propose to add additional info to preprocessing test dialog that will give users "the final result" of preprocessing, including type casting like so:
