Hi guys, I want to add a list of SIGNED numbers... but I don't know how to tell the computer to ADD THEM as signed, let me explain further:
when adding 200 + (-100) , it becomes 100, but in asm the computer always add them as unsigned, so I always get the 300. Do I have to add them in a register, and do the two's complement ?
# how about using abs
abs(number) + abs(number)
That doesn't sound like expected behavior at all...
How many bits are these numbers? Could they be wrapping?
They are 32 bits but adding them in 2 registers so I can have a 64 bits number (with adc, in eax:edx).
I'm not sure that really works as intended. You might try adding in MMX registers to get 64-bit data.
