Assume we are using the simple model for floating-point representation as given in this book (the representation uses a 14-bit format, 5 bits for the exponent with a bias of 15, a normalized mantissa of 8 bits, and a single sign bit for the number): a) show how the computer would represent the numbers 100.0 and 0.25 using this floating-point format. b) show how the computer would add the two floating-point numbers in part a by changing one of the numbers so they are both expressed using the same power of 2. c) show how the computer would represent the sum in part b using the given floatingpoint representation. what decimal value for the sum is the computer actually storing? explain.
