Calculate by hand, assuming each of the values are stored in the 16-bit half precision format described in Exercise 3.27 (and also described in the text). Assume 1 guard, 1 round bit, and 1 sticky bit, and round to the nearest even. Show all the steps, and write your answer in both the 16-bit floating point format and in decimal.
Using a table similar to that shown in Figure 3.6, calculate the product of the octal unsigned 6-bit integers 62 and 12 using the hardware described in Figure 3.3. You should show the contents of each register on each step.
Using the IEEE 754 floating-point format, write down the bit pattern that would represent . Can you represent exactly?
Question: What do you get if you addto itself 4 times? What is ? Are they the same? What should they be?
