For this question, mark all answers that apply: Assume any float or int is stored in 32 bits and float arithmetic is as specified by the IEEE 754 standard for single-precision. Which of the following statements about floating point arithmetic are true? 1) Catastrophic cancellation can cause loss of accuracy in floating-point multiplication 2) If all values are normal and within range (a+b) must equal (b+a) 3) If all values are normal and within range, (a*b) must equal (b*a) 4) A too-large value can be represented as infinity 5) NaN can be used to indicate that a result is not a valid floating-point number.
