Does anyone know what Intel had in mind when they created the BCD
instructions for the 808x? As near as I can tell, the instruction
set supports only unsigned BCD. I need to do signed math in BCD.
Is there a better way than testing the signs and magnitudes, doing
unsigned math, and inserting the correct sign after the fact?
Thanks
