Odd averages

I need help!

[adni18]

I have a rating thingy on my website for each of my images in my image gallery. They are based on a scale from 1 to 10. Each time a user votes for an image, it adds it to the grand average and divides them all by the number of votes there have been. Here's the problem: every time someone votes, the grand average goes down to 0.846346937649367494694837494873. Someone please help!

Are you stating that the same number comes up all the time? Or that the average is decreasing?

Never mind. I figured it out. Thanx though!

adni18, what did you end up doing? I would probably use something like:

use Math::Round;
$rounded = nearest(1, (0.846346937649367494694837494873);

Well, I figured out I was adding to the GRAND AVERAGE then dividing. I needed to save THE TOTAL NUMBER OF POINTS then display the average by dividing it by the number of votes.
