So all Status values start as INT. And they work fine as INT, problem comes when you want to use Floats. When I go to Information Overrides -> Number Format -> Status Value Format and change it to Float with format '0.00', then use node Change Status Value -> Add -> eg. 1.35 value, it will still show it as INT, so 1. Adding other values will still keep it INT ofc.
Edit- also, if you set is as Float in the Information Override with Manipulator -> Operator -> Set -> Float Variable and use a float variable, it counts it (only here, it doesn't sets it if you do it in event), however doesn't update it in the Menu screen. You have to close/open it to see the new value, even when you have it updated by any change. Also, doesn't count it to the value, just sets it.
