I need answers to all the questions.

OAU16 is a 16-bit microprocessor machine that represents floating-point numbers using the following format: (i) The most significant bit stores the sign of the number, (ii) The next seven(7) bits stores the mantissa, (iii) The next bit stores the sign of the exponent, and (iv) The rest of the bits stores the exponent. (a) Discuss, by illustrating with diagram, the structure of floating-point number format in OAU-16. (b) Show how 25.62510 will appear in the memory of OAU-16. (c) Discuss the absolute, relative and percentage error that will be incurred by storing 25.62510 on OAU-16
