+Addressed an inconsistency in the usage of 'div' and 'mod' operations within the rule engine. Previously, the 'div' operation was only usable as an infix operation and 'mod' could only be applied through a function call. With this change, both 'div' and 'mod' can be used via function call syntax and infix syntax.
