To get some feel for the effects of denormalization and gradual underflow, consider a decimal system that provides 6 decimal digits for the significand and for which the smallest normalized number is 10-99. A normalized number has one nonzero decimal digit to the left of the decimal point. Perform the following calculations and denormalize the results. Comment on the results.
a. (2.50000 × 10-60) × (3.50000 × 10-43)
b. (2.50000 × 10-60) × (3.50000 × 10-60)
c. (5.67834 × 10-97) - (5.67812 × 10-97)
