Expressions allows to use mathematical formulas to be used in d3web knowledge bases. In every formula you may access existing questions and their values, as well as predefined constants. The results of those formulas may be used to assign it to an existing question or as a precondition in a rule.

* __<object-name>!~[<time-point>, <time-point>~]__: \\ Returns the strict sub-history of the object with the name <object-name> starting from the earlier of the two time-points and lasting to the latter one. The sub-history contains all values of the object's full history that have been set during the specified interval. In contrast to the 'normal' sub-history, this strict sub-history will not maybe start before the specified earlier time-point, but only at that earlier time-point or later (but of course not later than the later time-point).
