17. Assume an 8-bit floating point format where the result must be properly represented (where possible). Our 8-bit format uses the first bit for a sign, the next 4 for an exponent (bias=7) and then 3 for the fraction. 10 marks total Convert the following into base 10 (or if you can't, try, and explain what went wrong.) A. 0 1001 101 B. 10101 100 Perform the following calculations in our binary floating-point format, your answer should be in our 8- bit minifloat format, and your steps should be in minifloat.
