I will add something like Number>>percent
^Percentage of: self

And Percentage value should be The number / 100, the printOn: can show the % sign, something like '50 %'. Obviously this must behave exactly as a number. This allows to be extended in case something specific is needed for percentages. (I can use it in RenoirSt and remove one of the extensions I have)

Too bad % is used as a binary selector :( . Writing 32 % is a lot better
