Exercise 1.17 Let's start the discussion with a very concrete example. Consider the number I= -123.15625 (in base 10). As we've seen this number can be converted into binary. Indeed I= -123.15625,0 = -1111011.00101, (you should check this). a. If a computer needs to store this number the first they put in the binary version of scientific notation In this case we write b. Based on the fact that every binary number, other than 0. can be written in this way, what three things do you suppose a computer needs to store for any given number? c. Using your answer to part (b), what would a computer need to store for the binary number 10001001.1100110011
