Accuracy And Bounds Flashcards
1
Q
What is the lower bound (LB) of a value?
A
The smallest number that would round to a value.
2
Q
What is the upper bound (UB) of a value?
A
The smallest number that wouldn’t round to a value.
Exception: when working out a question about humans, the UB will be the largest number that can round down to a value (because you can’t have .99999…. of human).
3
Q
What would the max and min of x + y be?
A
Max: UB + UB
Min: LB + LB
4
Q
What would the max and min of y - x be?
A
Max: UB - LB
Min: LB - UB
5
Q
What would the max and min of xy be?
A
Max: UB x UB
Min: LB x LB
6
Q
What would the max and min of x/y be?
A
Max: UB/LB
Min: LB/UB
