Our requirement is to display facts exactly with one decimal place. To reduce effort and since the feature is often needed, it shall not be a matter of configuration within the properties in the grammatic layer of a canvas.
Instead it shall be modelled as function within the semantic modeler. We now observed that it is partially possible by setting a Round-Function in combination with cast. E.g. we want exactlcy one decimal place in fix, also in case of X,0 (1.0)
But when we then use the fact in a canvas after modelling the round and cast function, the number of decimal place is only set as 1, when the number has not a '0' at decimal place (again the example of 1.0). So facts are either displayed as e.g. 1.5 (in case of not 0) or as 1 (in case of 1.0).
We need the fact in any ways, that it is displayed with one decimal place, e.g. 1.5 or 1.0 without the need to configure the properties in the canvas.
