In this paper, we study the existence of almost and quasi-periodic solutions to two classes of second-order di erential equations. As a corollary, it is shown that periodic and unbounded solutions can coexist for the equation x (t) + ! 2 x(t) = bx([t]) + f(t), which is di erent from the case: b = 0.
