Phantastic Program! One bug



Dear Friends!
Thank you very much for this great program.
I have a sabbatical at Riga Technical University and they did not have
any Computer Algebra System.
So I asked all my students to download Maxima.
However, there is one bug. The net present value does not seem to work
very well.
This gives 2 different solutions

load("finance")$

npv(0.03,[-1000,0,0,0,1200]);

-1000+1200/(1.03)^4;

I included the calculation in the attachment.
If there is anything I can do for you, please tell me.
I am not much of a mathematician, though.
I am an economist.
Bye,
