Pledge Balance Based on Expected Installments vs. Actual Payments Caused Incorrect Balance Calculations

This issue was reproduced in the 4.6.9 demo environment - link to pledge is: http://d46.demo.civicrm.org/civicrm/contact/view/pledge?reset=1&action=update&id=5&cid=202&context=pledge&key=dc985d84e52387b8136e24d24947309a_1350, screen shot also attached in case it gets wiped before you are able to view it.

To reproduce:

1. Create a new pledge for a total of $100 to be paid in 12 monthly installments (calculated as 8.33)
2. Record a payment of $100 against the first installment > this results in a balance of 4 cents left because 8.33 x 12 = 99.96

Perhaps a validation should be included in the pledge balance calculation along the lines of if paid amount = pledge total amount, DO NOT calculate balance based on pledge total less expected installments, then mark as complete?

Thanks as always!
