What's the 2's compliment of 11010 Here the first bit represents the sign bit ??

Question

I have a problem related to signed and unsigned numbers any one knows how to convert in 2's compliment ?

Answer 1

@gordie we apply the xor operation to sign bit also ?? means the first 1 that is representing -1 also get changed after applying xor or we doesn't include the sign bit in xor operation ?? but in your soln you have used xor operation in sign bit also ??

My confusion is that sign bit also get changed by changing whole 11010 into 2's compliment ?

Answer 2

@Gordie Thank you !! thanks for d help !! it's for my semester exams :-)
