The warnings below were produced by the tests. Looks like it results in the last step being missed out.

Looks like the original numbers check out correct as floating points, but the way optuna checks is by converting to strings and decimals, and guess then rounding error occurs. Could either do something similar and ensure to round high value up; or just adding on a small number would probably do (some small multiple of step) but then warning would need supressing.

Looks good and works well for me!

If it doesn't break anything it might be worth adding the action_from_value method to the RealNumberActionGenerator, as otherwise I think it only exists in the DwellActionGenerator. (this is also a problem for both of the scipy sensor managers so there might be a reason we didn't, I can't remember!)
