[eclipse-clp-users] Excuse me. I want to ask a question.

Hi

   I want to ask a question. That's I want to use ECLiPSe in JAVA(eclipse).

   But when I use the instruction  "rpc(remote predicate call)" in ECLiPSe
that just return "null".

    It's can work in integer number but can't work in real number.Can I ask
why? Thanks for your help.

   If I want to solve the answer in  real number domain as follow



  :- lib(ic), lib(listut).

testTriangleTriangle(Path, OState, Arg, Result, NState) :-
Path > 0,

[Sc] :: -127.5 .. 128.5,
[NSc] :: -127.5 .. 128.5,

NState = [NSa, NSb, NSc],
