Scavs

Sorry for the interruption a question:

I see a "new" baseball stat from what I was used to.

What is 0.1 Innings pitched? It has to be 0.333 repeating
Innings pitched right (with one out)? Or they just use .1, .2 and .3 and then
you are back to the whole, in other words a base 3 number system
instead of base 10?

I was used to 1/3 or 2 2/3 Innings pitched.

Have I screwed this all up?
