haha instead of adding and substracting 1 , it's even better adding zero, I understand what you are talking about, but there is really a need for me to convert to number while I am using the module, Language::Prolog::Yaswi, to convert the perl datatype into prolog dataatype, which is another language. If I did not do so, it would treat that as string instead of number. So I think there is not better way than adding 0. Thank you.
