Modern Prolog libraries have handled the issues of unidirectional integer predicates, so the old ways of handling numeric values is not relevant for most problems.
- jfmc 2y agoMany times the algorithm that you are implementing requires a precise data flow that is not reversible, so using traditional arithmetic (is/2) is better for catching errors. On the other hand CLP(FD) is not new at all (it is very popular for constraint programming).
- rscho 2y agoWhy would it be better for error handling? If you'll be using unidirectional flow only, then the point is moot. But using clp is arguably better IMO, allowing type and range checks while allowing relational execution.
