I have a strange problem when trying to calculate function IRR. It gives me
a divide by zero error, which I don't understand. According to the help-file
it shouldn't be able to give me this error. It occurs when I insert the
following numbers into cells A1 to A11.

-10687
-44634
-45750
-5249219
1669875
1249913
11050
878220
815253
=IRR(A1:A10;0.25)

Can someone explain why this happens?

Thanks in advance
