ACTION: Counting each system, convert from one system correctly to another, express systems with signed numbers in binary sign magnitude and carry out several arithmetic operations, including 1's and 2's complementing. Conversions Example: Convert from decimal to sign-magnitude. The first time assume that the numbers are in unsigned positive integer format. 00000000009. Best Answer: Sign and magnitude requires two things: 1) Sign (0 = positive number, 1 = negative number) 2) Magnitude (the number being represented) 95 decimal = 000001011111 binary (note the leading zeros added so that 12 bits are used) -95 decimal = 100001011111 (just change the first 0 bit to a 1).
