Extracted text: A computer architecture uses 6 bits for exponent and 9 bits for fraction and 1 bit for the sign. a) How is the value -13.75 is represented by this architecture? Show the hex value. Show your work. b) Represent the largest de-normalized positive number in this architecture in decimal. Show your work. C) Assume m, n and q are double type variables, write the code: Note you must first convert to postfix and write the code accordingly. m =n (m + q)/ m
