Issue

This Content is from Stack Overflow. Question asked by Roe

I’m having some difficulty understanding how I would go about doing this. I’ve been given some binary numbers to convert to decimal with the question saying:
Convert the 2’s complement numbers below to decimal

#1 : 1001

#2 : 0010

For #1 I know you would just take the 2’s complement to find the magnitude because the 1 indicates it’s negative. So it would really be 0111 or -7. What I’m having trouble with is if I should do the same process with #2. It’s not negative so I don’t know if the problem wants me to instead take the 2’s comp or if the decimal would just be 2?
