I would therefore expect that you don't need to do anything different for handling these the same way as you handle the predicate calls -- are you getting different results for the two cases? On further digging, seems to be a know bug. Looking into the "iso.pl" file I found the following comment: %----------------------------------------------------------------------- % 9. Evaluable functors (incomplete) % Note: the redefinitions of floor,ceiling,round,truncate don't work currently, % the arithmetic transformation in the ECLiPSe compiler always uses the % sepia_kernel definitions for the predefined arithmetic functions! %----------------------------------------------------------------------- Thus, it doesn't sound as something that I can workaround on my side.
