One of the strength of RDDL is it intuitive way of using math inside CPFs. Numerical state fluents are absolutely necessary to make use of that, currently it is only possible in the reward function. (issue from 29.03.2013)

I can see integers with small domains being supported soon, large ints and reals will still take a while. (comment from 20.02.2014)

We have both a PROST version that supports enums and one that supports numerical fluents, but merging them is no straightforward task. (comment from 20.09.2013)

Another issue on the same topic was opened (and closed again) here.

@fdouglis, we are always trying to enhance the planner, but I honestly do not believe we will anytime soon add numerical variables to Prost since it requires a fundamental re-writing of most of the core functionalities of the planner.

Ok, thanks very much for the feedback.
