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.

    (2/2) In the case of 0.2% and 2/10%, the "%" _describes_ the preceding numbers--it tells us that we are talking, in both cases, about a _proportion_ of measured thing, and that the 0.2 or 2/10 are the numerator, and 100 is the denominator, of that proportion: 0.002. Similarly, _describing_ a number 0.2 as a proportion tells us it is *not* a percentage. "The proportion M&Ms in the candy jar is 0.2." Means the same thing as "20% of the candy jar is M&Ms". Compare to "The _decimal_ of M&Ms in the candy jar is 0.2."--not only is this sentence different in meaning, it is nonsensical.2016-05-19
