The test was implemented and integer blank values are now correctly accounted for. The commit has been pushed to master.

When binary operations like +, -, * and / are requested, the Arithmetic library (and thus program) doesn't take into account blank integer values.

For the unsigned integer types (where the blank value is the largest value of the type), this can give some strange results which can be confusing. A check is being written to take integer blank values into account.
