Enum values from live.dial to use correctly

Hi folks, this is my first post here, please be patient with me. I just recently learned some basics..

So I want a live.dial to have certain values only and I want to use those values in a multiplication.. so I chose Enum right? But the live.dial only outputs raw values 1-24. (when I put a numberbox after I get 1-24)

The values I want to use in the multiplication are:

0.5 0.53 0.56 0.6 0.63 0.67 0.7 0.75 0.8 0.83 0.89 0.94 1. 1.07 1.13 1.2 1.25 1.33 1.42 1.5 1.6 1.67 1.8 1.88 2.

Live.dial shows those values but outputs only 1-24, as I said..
There must be some way to get exactly those Enum values out, right?

Thanks in advance,
S.
