Question 4. Given the IEEE-754 Single Precision Floating Point number (saved Excess-127) 011111000101011000000000000000002, determine the following a. The sign of the mantissa b.The magnitude of the exponent convert to base 10) c. The sign of the exponent Question 5 Given the IEEE-754 Single Precision Floating Point number (stered Exces-127) 10111100010101100000000000000003, determine the following a. The sign of the mantina b. The magnitude of the exponent (ectivert to base 10) c. The sign of the exponent Question 6. Using an online cativersion calculator, find the mantien valtus of the IEEE-154 Single Precision Floating Point numbers from Questions &5 Question 7. IEEE Hosting point numbers will occasionally yield incorrect math resalts when used in computer programs. Using your Raspberry Pi open the interpreter by typing the word python in the command line. You will get a prompt that shows >>> Start, for example, >>> 0.1+0.1 Then try something like >>>0.1.0.2 CNTT 17600 - Intro Computer Architecture - Floating Point Lab >>>0.1.0.7 >>>0.3+0.6 >>>0.2+0.7 What happened when you tried to sim these pairs of sombers Stammarize these results in a table. Explain why this happened. Use lecture notes and other resources to find the CIL of this phenomenon
