How to close partial paid invoices

Hi,

Back in 2000, my company did conversion from legacy system/non erp to Oracle financials. At that they did some manual transactions..  and they data amounts precision to 3 digits.

Now there are some transactions like this :

For ex:

Invoice Amount : 25.49

Paid Amount : 22:30

Discount : 3:20

There is a penny difference. In this case one penny more.. but there are some invoices with a penny less.. Now these invoices are marked as Partial Paid. How to close these invoices.

I have about 5000 invoices with this category.

Any help is appreciated.

Thanks
