Limits of accuracy or bounds are used to describe all the possible values that a rounded number could be. Similarly, a lower bound is said to be a tight lower bound, a greatest lower bound, or an infimum, if no greater value is a lower bound. Meanwhile some articles have given explanations for Upper /Lower bound of Worst Case. For instance, if a function has a lower bound, it means that its values cannot drop below a specific limit, regardless Lower bound definition: .
