230, CSCE Spring 2009 Homework 2 (Chapter 2) Due: Tuesday, 2/5/2009 before class Note: Recall from the syllabus that: 1. Although homework assignment s carry a relatively small fraction (10%) of the course, doing them will certainly help you in doing well in other parts of the grade which carry much larger fraction of the course grade. 2. You are encouraged to work in groups to discuss the homework but be sure to write your own solutions and note down, on the cover page, who you worked with. Most problems on this homework come from the exercise at the end of Chapter 2 and each problem has the same weight. Problem 1. Do Problem 2.6.1 to 2.6.3 only for part (b) and 2.6.4 to 2.6.6 for both parts (a) and (b). Problem 2. For this problem, assume integers are represented 6 using bits. Further, for signed numbers, assume the leading bit represents the sign bit. (a) Determine the range of numbers that can be represented for each of the following notations: unsigned, sign-magnitude, and 2's complement. (b) Represent -15 in the following notations: Sign-magnitude and 2's complement. (c) Show the steps of the computation A B in 2's complement notation, where the decimal value of A is 12 and the decimal value of B is -13. Probl...
