Scoring with non-integers and score percentage

Hello there!
I'd like distribute the scoring points among the answer options of a single question such that the maximum possible score for that question adds up to 10. This means that, e.g., if I have 4 correct answer options, each of these options needs to get a score of 2.5.
However, when I enter 2.5 in the scoring field, Qualtrics rounds this off to 2. I had assumed this was just a representation thing and only found out later that the scores are not as high as I want them to be.
In addition, I then want to calculate the score of all the questions as a percentage: If I have N questions with 10 points maximum each, the overall percentage score would be S = (score)/(N*10), which I calculated in an embedded data field. Because Qualtrics rounds off the scores to integers, it now becomes impossible to reach 100% total score.
My questions therefore:

  • Is there a way to circumvent the rounding in scoring, i.e., a way to use non-integers for scoring?

  • Is there a better way to represent overall scores as a percentage with respect to the maximum possible score?

Thanks for your replies!

Qualtrics does allows the score in decimal points.

rondev Thanks, you're right, it was a stupid confusion with decimal point vs decimal comma.
Can you maybe also help with the second part of my question, the percentage score?

(score / (N*10) ) * 100

Thanks again, that's what I'm currently doing as an embedded data field. However, I was wondering if there is a more Qualtrics-like way such that it is, e.g., not necessary to manually update N if the number of questions changes.
I guess it does not exist but maybe it could make a nice new feature.
