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 18 in this format. The answers were posted in another chegg question below: +1.7 = 001111101101 0.012 = 101000100010 19 = 010011001100 18 = 001100000000 How are these answers obtained?
