not a so simple design ...
Hi, Steve
As a 0-100 scale is expected, ... RCTime function could do it.
Buuuut, the problem is light scale ... it's a logarithmic scale !!!
Sooo.... the input scale must be 0 - 10 000 !!! ( which is the A/D to use, Then ???? )
I think a design around a CA3089 ( or with log response: FM IF systems w/signal stenght indicator make good sonometers ...) could do it easily.
here, a modular 3 1/2 digit std voltmeter could be enough ... as the CA3161/3162 are ... out of my purse !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
