3. Show your work when answering this question dealing with IEEE Std 754 32-bit binary floating point numbers. This is a theoretical exercise demonstrating that you understand the concepts. Using a format/approach similar to that found in the 412-L02 slides dealing with IEEE 754 floating-point representation. (a) Show the 32-bit hex representation for the decimal value 11.25 (b) Show the decimal value for the hex representation 0xco700000 (c) Show the addition of the two values in parts a and b. (d) Show the multiplication of the two values in parts a and b
