Thank you! In the meantime I also tested it and an example output where it actually fails later is ``` k*k >= 1.0, info: 1, 0.000372094, 0.0085, 0.00662791, 0.0085, 0.007,...

One could btw. potentially add a `TermType fType;` member with an enum `TermType` to controls/terms that classifies which type the control has, and then check if this type is equal...
