4. Convert the 8-bit signed 2's complement hex number 0x3F to decimal: 5. Convert the 16-bit signed 2's complement binary number 1001 0001 1111 1010 to hex: B. Representing 2 in a fixed-point register with 2 bits for the integer part and 3 bits for the fractional part gives a round off error of most nearly (1) C. An engineer working for the Department of Defense is writing a program that transfers non-negative real numbers to integer format. To avoid overflow problems, the maximum non-negative integer that can be represented in a 5-bit integer word is (1 mark) D. For a numerically controlled machine, integers need to be stored in a memory location. The minimum number of bits needed for an integer word to represent all integers between 0 and 1024 is (1) E. Add the 8-bit 2's complement numbers 1110 1001 + 1100 0010. State the result of the addition (as a binary value), as well as whether over- flow occurred if the number were treated as signed, and whether overflow occurred if the numbers were treated as unsigned. Show you work. (2 marks)
