1. Convert the decimal numbers in the calculations below to single-precision FP format and perform the calculation. Check your work by converting the FP result to decimal. Show ALL work for full credit. (80 pts) a. 38.1 + 187.657 b. -3.672 +1023.985 C. 468.513 - 0.8 I d. 3.5 * (-95.627) 2. What is the result of multiplying the following IEEE-754 single-precision FP numbers? Write the complete procedure in reaching the final result for full credit. If any rounding is needed, use the GRS bits to "round to nearest". Write the final result in both binary and hex. Convert the original FP numbers below to decimal, perform the multiplication operation, and check your results for correctness by converting the decimal result into a IEEE-754 single-precision FP number.
