Section 6.3
Review Questions
Signed binary numbers (integers)

---

1. What are the two major ways to encoding signed binary numbers discussed in this section?

2. What is -15 written out in 8 bits using sign-magnitude form?

3. Suppose your registers were only 16 bits long. Could you put -500,000 into a register using sign-magnitude form?

4. What do we call it when we add 0s to the front end of a number, which does not change its value, so that it will have the required number of bits?

5. What spurious number exists in 1's complement but not 2's complement?

6. How do you go from ordinary binary to 1's complement? For example, 01111 is 15. What would -15 be?
