It’s a little bit confusing for me and others to understand the mathematical summary behind the percentages. I’m the opinion that all answers per poll should result to 100% and not 200%. Even for two votes. That’s not logical. Is this a bug? [afbeelding]

Wasn’t this just fixed? [afbeelding] Polls percentage accounting is not accurate bug It seems when calculating percentage for each option in polls Discourse uses floats truncating instead of rounding. This can result into inaccurate percentage values. For instance, a poll …

I’m running the latest-release +59. :frowning:

The meaning of that poll result is: 49% of all voters selected “Montags” 24% of all voters selected “Dienstags” … This seems to be a multiple choice poll, so it is perfectly normal that the sum of the percentages is greater than 100%. But the -1% definitely looks like a bug.

Can someone explain me the math behind polls?
