Message:

#2301 Use decimal instead of double for the DefineArithmeticProgressionDialog and in the CreateExperimentDialog.
Note, when using decimal only during the generate process but not during some calculations (e.g. determining meaningful step sizes), numeric inaccuracies occur.
Therefore some calculations now uses decimal instead of double values.
