Am a self teaching Newbie Assembly programmer :) Still in the theoretical Stages.
My question is....
According to the book am reading
When you convert 254(decimal) to hexadecimal you get 0FEh.
And when you convert -2(decimal) to hexadecimal using two's complement you get OFEh.
When i do it manually i get FEh.
Is the zero before FEh always necessary or is it just another way of representing your code..?
Am fully aware that 0 in hexaecimal stands for 0000(base 2)
Thanks in advance......
