Audio use a slider to change DB on a mixer?

i wish to use a slider to change the AudioMixer Values, the AudioMixer range is -90 to +20

so to do -90 to 0 is a simple

Code (CSharp):

1. 20.0f * log10(sliderPercentage);

but to get it to +20, i cant figure it out, unless i do a if(DbIWant > 0 ) kind of thing



so i can use a normal slider next to this and get the correct decibels

 

It's sad that nobody has gave an answer to this question in years, but I just had this problem and got a solution on my won, which is very funny, but works with exactly this piece of code you have just asked for. I see you are still active in 2020 and i`m sure this might help you and many other people, so here is the answer:

In the "Slider" UI element in the inspector set the max value to ~6 (or more) somehow it works, maybe not the best solution but it works. Here is a screenshot:
