on scenario 1 at 9:18, the two negative numbers added obtained a negative result so wouldnt there be no overflow?

look at 4bits, not 5 bits.

Oustanding course. Interesting at 05:10, with overflow due "10" instead of "11".

I 3rd scenario is confusing since the first scenario is giving a different point .

is the s2 is coreect that show -8 ... if msb indicates sign represents then its result -0;

In s1, -16 +6 = -10 which is same as -7-3 = -10. How did s1 became overflow? Both -7 and -3 are -ve numbers and result -10 is also -ve

ig when we are adding -7 and -3 , the bits we are getting is 5 bits ,if you discard the leftmost 5th bit the leftmost 4th bit represent the sign bit in 4bits representation in signed int, so leftmost 4th bit is zero which represents positive sign but the result is negative , correct me if i am wrong .

Our teacher said when adding two negative number answer will be positive and overflow will occur, when adding two positive number answer will be negative so overflow will occur

Why there is no overflow in 3rd example?

@reallybadsupport2215 Жыл бұрын

My guess is that 0 is in the range of -8 and 7 so there isn't any overflow

@@itsoknottobeok9381because you'd need one more bit to display the result. -3 and -7 use 4 bits each, whilst -10 needs 5 bits, thus the overflow.

Why is the first 2^n negative? I am just picking up the topic of overflow, can someone explain?

@pancito3108 Ай бұрын

if you want to represent negative numbers in binary, one way is to use two's complement, and that representation is equivalent to making the msb (most signifucant bit) negative

Good explanation. Question! If I subtract two unsigned numbers e. g. 2 - 7 in binary 0010 - 0111 I guess that I can not caluclate the result because I have unsigned numbers. They are always positive. What happens in this case. Is there a carry? Is there a overflow? Thank you for your help in advance!

Useful information : When you add two different signed numbers you never get an overflow

@wajeehullah4371 Жыл бұрын

I think you have made a mistake in S1. We would consider 4 bits of the result only 0110 and this would sum up to 6. Now since we know that we added 2 negative numbers and the result we got has a positive sign (+6) so now we will say it is a case of overflow as we would need 5 bits to represent -10.

s3 indicates cancellation between 2 units of 2^2 and 1 unit -2^3 hence the cancellation, voiding it to zero. The method you used makes it confusing and turned it into a fake overflow scenario, scenario one by no means appear positive, it's all negative wdym? Did u mean the 0 at 2^3 spot? Then circle properly. I'd suggest you guys to just use common sense and check if answer fits the range to determine overflow, his scenarios will make u fail ur tests in confusion
