Could you please help me with question 21 from chapter 9? Computeranization and embedded systems Hamacher 6th edition.

In Section 9.7, we used the practical-sized 32-bit IEEE standard format for floating- point numbers. Here, we use a shortened format that retains all the pertinent concepts but is manageable for working through numerical exercises. Consider that floating-point numbers are represented in a 12-bit format as shown in Figure P9.2. The scale factor has an implied base of 2 and a 5-bit, excess-15 exponent, with the two end values of 0 and 31 used to signify exact 0 and infinity, respectively. The 6-bit mantissa is normalized as in the IEEE format, with an implied 1 to the left of the binary point.

(a) Represent the numbers +1.7, 0.012, +19, and 1 in this format. 8

(b) What are the smallest and largest numbers representable in this format? (c) How does the range calculated in part (b) compare to the ranges of a 12-bit signed integer and a 12-bit signed fraction? (d) Perform Add, Subtract, Multiply, and Divide operations on the operands

A = 0 10000 011011

B = 1 01110 101010
