Allow Speed multipliers with decimals

[vonglan]

Low prio.

Would it be easy to allow speed min and max with decimals? For the incremental button use case, if the target is bipolar, my usual value of 20 does not work, because then the neutral position is not reached. It would be nice to be able to use 12.5.

Alternatively, I could use 25 (quite big jumps) or 10 (more knob-pressing).

Wouldn't be difficult to implement I guess.

I'm using 10 now, so no rush.
