Quick question :)

I have 3 variables:

a - current rating of item
b - total number of votes for this particular item
c - new rating to update current rating with

Something has rating of a, and total number of votes b. Someone just rated this something at c. I need to recalculate rating a considering new rating c.

"Среднее арифм." obviously wouldn't do it.

Anyone? :mrgreen:
