Description Stephen Weinberg 2011-09-05 02:04:43 UTC 
According to the about page, I am running GnuCash 2.4.5 build from r20528M on 2011-04-12.

Steps to reproduce.

1. click Tools -> Loan Repayment Calculator

2. Set the following (in case it is not obvious, I am using US punctuation)
   Payment Periods:   Blank
   Interest Rate:     8.5
   Present Value:     11,000
   Periodic Payment:  -5,000.00
   Future Value:      0

   Compounding I left at the default (Discrete Monthly)
   Period I left at the default (End Monthly)

3. Click Calculate.

You should receive a payment period of 2 and total payment of -10,000

What is wrong with this answer? That does not match the "Future Value"! The Future value will be 0 in this scenario when a total of $11,128.91 has been paid over a 3 month period (last month being $1,128.91).

I would love to get into how awful making the payment negative is (just a new label or *-1 would fix that.). There are also a few other usability problems but that is for a enhancement bug report.

Reassign version to 2.4.x so that individual 2.4 versions can be retired.
