Problem 5 (2 points) but not necessarily representable in single precision. Assume that u is read as an input and stored in single precision. Derive a bound for the relative error in (x + y)/u. (Assume no overflow or underflow occurs.) Let x and y be IEEE single precision numbers. Let u be real, Problem 5 (2 points) but not necessarily representable in single precision. Assume that u is read as an input and stored in single precision. Derive a bound for the relative error in (x + y)/u. (Assume no overflow or underflow occurs.) Let x and y be IEEE single precision numbers. Let u be real
