Accumulator - Max and Min Limits

I want to map an object position to a thumbpad axis. Accumulator behaves exactly the way I need so thumbpad (-1,1) values map to (-,+) decreasing or increasing values. The problem is the lack of a Min Value parameter clamping the object in one direction. While I can clamp the Max distance, the Min distance will continue to infinity. Any workarounds for that?
Min/Max settings would also be handy in the Continuous Modifier.

I had the same problem. Spent a lot of time trying Notch logic but ended up using Javascript node.
