Machine epsilon, or just for short, is defined as the largest floating-point number x such that x + 1 = 1 in floating-point arithmetic. The experiment we did in class showed that is approximately 1016, which is why we say that IEEE floating-point can be accurate to about 16 decimal digits. What is the exact value of ? (Your answer should be an exact arithmetic expression, not a decimal expansion.) What is the 16-digit hex representation of in the IEEE standard? How close is to 1016
