How do sites like PokerRoom calculate their rake to points conversion

[Godfather80]

I know already that at my NL25 game every $.10 of rake = .07 points. My question has to do with how exactly the site distributes the points. For example, I sit down and play 1 hand where the rake is $.25. How does the site credit me?

Do they round down and give me .14 points? Do they accurately credit me with .175 points? Since PokerRoom's account page only displays points in whole numbers, I'm curious to know if I'm getting screwed or not.
