Knob widget: the update is stopped.; Decimal places are not displayed

I use the widget knob with great satisfaction.

But there were two restrictions. To overcome this I need your experience.

1: if the configured limits are exceeded, the update is stopped.
My case: 99% of the value is in the min…max / floor…ceil range. However, individual peaks rarely occur. This peak stops the update.

2: Decimal places are not displayed (% .2f is parameterized) but only one decimal place is displayed.
