I play video games; I need to know if the percentage is additive or multiplicative.

"+100%" looks pretty good until you see what "×25%" actually gives you.

[–] [email protected] 14 points 18 hours ago (1 children)

×25% gives you 1/4 the original value, whereas +100% is double the original value, let's say 8/4 to keep it consistent. ×125% (in case a 1 is missing) is still only 5/4 the original value.

Is there a typo in your comment?

In video games they commonly use that to mean they are multiplying by 25. We know it's not correct in stats. This is why game wikis commonly put the actual formula for things rather than the tooltip the developers wrote.

Biggest lie in a game's tooltip/description of an item was how the formula for Armor Piercing rounds in Fallout 1 and 2 was bad, so instead of being stronger than regular rounds, they were weaker.

Games use x25% or x25? Technically the first divides the score by 4.

We are aware of what it actually does mathematically. Please re-read what I wrote.

I was asking for clarification. Do many games really add the % to x25?
