Forgive me if you would rather see this in the console section, but it more pertains to mathematics than Video games. I'm just using CoD as an example for this.
Okay, so KDR.
Easy enough, to find your kill to death ratio, you just divide your kills by the number of deaths you received.
20/1 = 20 KD.
20/5 = 4 KD.
So my question is, what's the KD on a 0 death game?
Is it just infinite? Or is it incalculable?
On Black Ops, I'm sure it says your KD is the amount of kills you received if you have 0 deaths, but that just doesn't seem logical by the formula.
