Lets say I want to represent 20 Percent

What do you call/name the "0.2" and "20%" notations

I am calling them Fractional and WholeValue notations for the time being, but wondering if there was something better.

I would call "0.2" the decimal notation, and "20%" simply the percentage notation.

I would call "0.2" a proportion and "20%" a percentage.
