1. a) The stellar disk of the Milky Way Galaxy is approximately 100,000 light-years in diameter (1 light-year = 9,460,730,472,580,800 meters). Use the function to estimate how accurately this diameter can be defined in meters when using the IEEE double and single precision numbers;
  2. b) Use the and functions to find the largest floating-point number in IEEE single precision, A, and the distance from this number to the preceding single-precision number, B, respectively (A B A ). Use the function and specification to display A, B and A−B.
