a. Consider a fixed-point representation using decimal digits, in which the implied radix point can be in any position (e.g., to the right of the least significant digit, to the right of the most significant digit, and so on). How many decimal digits are needed to represent the approximations of both Planck's constant (6.63 × 10-27) and Avogadro's number (6.02 × 10-23)? The implied radix point must be in the same position for both numbers.
b. Now consider a decimal floating-point format with the exponent stored in a biased representation with a bias of 50. A normalized representation is assumed. How many decimal digits are needed to represent these constants in this floating-point format?
