What do 1<0 and 1=-1 mean in clingo/ASP?












0















I have never used clingo before, and I find the online documentation incomplete (I also can't post to the Potassco forums). I have a piece of clingo code with lines of rules of the format




foo(L1, L2, L3) :- isa(thing,object), isa(thing, object)...




That part of the code makes sense, but at the end of the line before the final rule, I have the conditions either 1>0, 1<0, or 1==-1. I'm not sure what they mean, because they don't seem to follow normal boolean rules. Does anyone know what this means specifically in clingo?
