What is the number that is actually stored in Problem 1.15? What is the round-off error?
Problem
Write the number 256.1875 in the 16-bit IDDD-643 standard that was introduced in Problem 1.13. Apply chopping if necessary.
Problem
Suppose a new standard, the IDDD-643 standard, is developed for storing numbers in a string of 16 bits. The first bit is used for the sign of the number (0 if positive and 1 if negative). The next five bits store the exponent plus the bias, and the remaining 10 bits store the mantissa. The bias is 15 and no bits are reserved for any special purposes. What is the smallest exponent that can be stored?
