For Question 2, I know the math equation: Exponent = power + bias. But in this question, I only know 15 bits for the exponent. so I even do not know how the exact value of the exponent and the power. So I can not get the answer for 2^14-1

For this Question, I can get the answer for 11001011, but in all options in question, I can not choose that. The correct answer is 1101 0010. Why?

For this question, I changed 11010111 into scientific notation for -1.11*2^3 so that we can get -1110. The final answer, I think, is -14. Why the final answer is -15?

Question 2 5/ 5 pts Quadruple-precision floating point has 1 bit for sign, 15 bits for exponent, and 112 bits for fraction. What is the bias? 2111 215 215-1 2112 214 2112-1 214-1
