Consider a 32-bit number stored in a byte-addressable memory as shown in the table below (note that the value is written in hex format): a. If the machine is little endian and uses 2's complement representation for integers, give the decimal representation of the 32-bit integer that starts at address 100. b. If the machine is big endian and the number is an IEEE single precision floating point value, give the decimal equivalent. Note the following: • When converting the binary significand to its base 10 equivalent, you only need to use the first 8 bits (not all 23) The final answer should be written as a simple real number (i.e., not in exponential format), with the fractional component rounded to 2 decimal places (e.g., 126.46 or -9768.83) Value Address 100 101 102 103 40 92 9C FB
