Hex to Signed Decimal (cont)
STEP 2 (positive sign): If the sign is POSITIVE, then just convert the hex value to decimal. The representation is the same for SM, 1s complement, 2s complement. $64 is a positive number, decimal value is 6 x 16 + 4 = 100.
Final answer is +100 regardless of whether encoding was SM, 1s complement, or 2s complement. $64 as an 8 bit signed magnitude integer = +100$64 as an 8 bit ones complement integer = +100$64 as an 8 bit twos complement integer = +100
