â¢ The greatest integer (or floor) function and its graph, seen in calculus and computer science, exhibit similar features. â¢ We will take a peek into calculus and preview the related topics of one-and two-sided limits and continuity. Piecewise-defined functions appear frequently in these sections of a calculus course.
