Fair enough. I happened to notice that some other nodes seemed to give the possibility of setting the control input although it might not make sense (e.g. some Div*Node and Mod*Node) and I thought it might be worth having a global look at this at some point.

This fix seems totally OK for me as it is now. Thanks again @merykitty.
