In the example given, (-1)%7 should therefore be 6.
It depends wether you focus on a arithmetic meaning of the remainder or on what you call "mathematics" (what would be "Restklasse" in german, I don't know the english term). In terms of "Restklasse" you want a positive modulo and get a negative division result. In terms of arithmetics you want a positive division result and get a negative modulo. Both are valid solutions. At the end you have to live with the definition of the given implementation. Just check the sign and correct the sign of the result according to your needs. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
