Description Andreas Fahle 2003-03-08 17:32:41 UTC 
GnuCash crashes when I tell the financial calculator to calculate the
interest rate, and the other values are such that the interest rate would
be zero. For example:
- payment period = 10
- present value = 10000
- periodic payment = -1000
- future value = 0
i.e. interest rate should be 0.

btw why is it impossible to enter a zero interest rate?

0% interest is not a Loan, it's just a limited-count scheduled payment.

Although you are correct that the calculator should not crash.

Reproduced in svn r13238. It's not actually a crash though, the code is printing "Zero Interest" to the terminal and calling exit(1) so gnucash shuts down (in preference to causing a divide by zero that would have followed on the next line).

I've committed a fix that prevents the shutdown and avoids the division by zero. The interest rate is shown as '-'.

Fixed in r13248.
