I tried this as a Custom Stat expression:
1 / 0.01
The answer (which you can see by adding the stat to a players report) is:
10.000000
Correct!
Then I tried this:
1 / 0.01
It says:
99.999999
Well, the answer we were looking for was 100. Judges? Okay, they'll accept it.
Then I tried this:
1 / 0.001
It says:
0
Uh. No, I'm sorry, the correct answer was 1000.
I have a hunch. Let's try just a hair smaller than the last value that worked, .01:
1 / 0.00999
It says:
0
So that's the borderline: .01 is the smallest that will work.
