Prolog - generating numbers fitting given range

Question

I\'d like to use predicates like:

range(X,0,5)
range(X,4,200)
range(X,-1000000,1000000)
dom_range(X,-1000000,1000000)

with meaning :

<

Answer 1

SWI-Prolog has the predicate between/3. so you would call it like between(0,5,X) to get the results you showed above. This predicate looks like this is implemented in C though.

If we have to write it in pure prolog (and speed&space is not a factor), you could try this following.

range(Low, Low, High).
range(Out,Low,High) :- NewLow is Low+1, range(Out, NewLow, High).
