What is the equivalent of -35 base 10 in a 8 bit 2's complement representation?

Question

help wld. be appreciated. thanks

Answer 1

To find the 2's complement, just flip the bits of the positive value and add 1, ignoring overflow.

+35 = 00100011

flipping bits makes it 11011100, then add 1 for the result of 11011101

Answer 2

ur calc.exe could be of great use...

start-> run-> calc->scientific mode

35 base 10 is 0010 0011

finding 2' of 35 will give value for -35.

so, -35 base 10 is 1101 1101

fine?. lets verify if this is true.

+35+(-35)=0.

so , 0010 0011+ 1101 1101 = 1]  0000 0000

ignoring the overflow, as our calculation is concerned for only 8 bits..
