As a programmer I usually want variable names that makes sense. I now stumbled upon a variable that can take three different values, so called three-valued logic.
In this case I am trying to name a variable that can indicate:
-1: Only others companies
0: All companies
1: Only my companies
It actually exist a fourth case, no companies, which I'm not interested in. For a standard boolean naming is easy, onlyMyCompanies, isOtherCompany etc.
Out of pure academic interest, what prefix (or suffix) would you use for a three-valued logic?
