Dear friends,

I have been testing the fixed point routines provided in AN617. I need to
execute 16x16 bit multiplication and 32x16 division.
Although division runs perfectly in MPLAB Simulator, the multiplication does
not. I set a breakpoint where I normally should be able to see the
multiplication product via a watch window, but the result is totally wrong.
Same thing stands also for 24x16, 24x24 multiplication, and I'm currently
testing the rest formats.

I am using MPLAB 6.30 and the project is built either for 16F84A, or for
16F876A.

I was wondering if someone has encountered this problem or used successfully
the multiplication routines of AN617. Any tips regarding this problem are
most welcome either via PICLIST or directly at:

nskentos@otenet.gr

Thanks in advance
Nikos
