Conversion of Signed to Unsigned

Question

How can we convert a signed number to it's equivalent unsigned number?

Let's say I have signed number as -2 now what would be it's equivalent unsigned representation.

 

Thanks!

Answer 1

See if you have number -2 in sign magnitude representation that means you can represent it as 110 here first 1 at MSB is for negative sign if you see this number in unsigned representation then that number is +6.

Answer 2

if n=-2 then it representation is 1110

to convert to equivalent unsigned number just complement it and add 1

1110->0001->0001+1=0010(2)

why -2 representation in signed number 1110 .

i think 1110 in 2's complement representation.

correct representation of -2 in signed format is 110 where msb 1 is used for sign.

and their corresponding unsigned representation is 6
