Changing win % to .400 instead of 40 %

Trying to get this win percentage shit to sync up to real life.

Preferably win %’s would be displayed as .400 instead of something like
40%. I read somewhere that I’d need to tell it that the precision is 3…
I don’t even know if I’m in the right ruby thinger.. BUT I’M TRYING!

Feel free to tell me how stupid I am, and that I should be looking
somewhere else. K cool, thanks.
