Hello community, I am bad at math!

I remember from when I was in school, it was something something 100 over a number? Haha, that's irrelevant right now...

Basically, uh. How do I type into string percentages?

How do I get the system to evaluate a number and give me the closest percent to that, and then of course "round" up or down?

I'm reading https://www.scirra.com/manual/126/system-expressions and also viewtopic.php?t=72716&start=0 as I wait for one of you lovely people to save me from my ineptitude of all things math.

Final question, what is the difference between the "Beginner's Questions" and "How do I" forum?

Percent means "per one hundred" so it is value/possible then * 100. So if you have 5 apples out of a possible 7, that's 5/7*100 = 71.4%

In C2 you can use the 'round' expression to round to the nearest integer (whole number). so round(5/7*100) would give you 71. If you want it to have the % symbol, just use &

So:

On Action---Set Text to round(5/7*100) & "%"

Will set the text of a text object to 71%.

Also, How Do I is generally (to me) for more in-depth questions whereas Beginnger's Questions is simpler questions for people starting out with C2.
