If you know how many answers there maximum is to a question you can store the answers
as integers to a common divider (does this make sense? I have no idea whatsoever these
things are called in english).
For example:
If you know there are gonna be from 1 to 4 answers to the various questions, the
common divider would be 12 as 1,2,3 and 4 all can be divided up into 12. The right
answer to a question with 3 possible answers, would be worth 4 points as 3/12th is 4.
To a question with 4 possible answers, it would be 3 points. 6 points for 2 and 12
points for the correct answer in 1 possible.
If there can be from 1 to 8 possible answers, the common divider would be 840 and the
points given corresponding to that (right answer out of 5 possible would give you 168
points). If you take the up-added points at any given time, mutiply with 100 and
divide by the common divider, you will have the percentage. And with no rounding up to
be nervous about as you are always dealing with integers when adding the points.
As to how you will find out which fraction an floating number is equal to, well, that
is a science it itself and should be handled carefully, or you might end up with a
score of 78 126/168 % and that is not very professional. Add to that, you could also
tell your customer that having percentage numbers in fractions is very controversial
and not how the percentage scale is supposed to be used. After all, percentage in
itself a converted fraction (it means "per hundred"), so 1 1/3 % really means "one and
one per third per hundred". In the ancient Rome they would have laughed their arses
off of this dumb tourist. ;-)
I really hope I'm making myself clear. I'm not very good with mathematical or
scientific terms in english, so I rely on you remembering your basic school math.
(which is tough for me once in a while ;-)
happy coding
