Unformatted text preview: ort pointer arithmetic, but the C compiler often uses it as a way to perform multiplication by small constants. For each value of , we can compute two multiples: can compute multiples 1, 2, 3, 4, 5, 8, and 9. Problem 2.22 Solution: [Pg. 65] We have found that students ﬁnd this exercise looks difﬁcult when working directly with assembly code. Formulating it in the manner we have shown in optarith can help clarify the behavior. We can see that M is 15; x*M is computed as (x&lt;&lt;4)-x. We can see that N is 4; a bias value of 3 is added when y is negative, and the right shift is by 2. Problem 2.23 Solution: [Pg. 68] Understanding fractional binary representations is an important step to understanding ﬂoating-point encodings. This exercise lets you try out some simple examples. Fractional Value ½ ¿ ¾¿ ½ ¿¾ ½½ ¾ (when b is 0) and ¾ ·½ (when b is a.
