Volume dimming value in dB

With some AV manufacturers, the volume is displayed in dB. In KNX, dimming with EIS6 0-100% is used to control the volume. Now the volume in dB is linear to the dimming value 0- 100%.
It is quite easy to convert this so that you do not have to do without the dB display.
The lower and upper values should be read when the setting is 0% and 100% respectively.

This logic group, can also be used for other ranges to map a display value range "from - to" with 0 - 100% (negative value ranges are also possible).

Input values:
- Lower limit (preferably as EIS 5, DPT 9.xxx, 2 byte float)
- Upper limit (preferably as EIS 5, DPT 9.xxx, 2 byte float)
- Dimming value (EIS 6, DPT5.001, 0-100%, 1 byte)

Initial values:
- Display, like input (EIS 5, DPT 9.xxx, 2 byte float)
