abstract = {Summary: By applying the floor and ceiling operations to real numbers, a real function can be discretized to give a new function on the integers. Much information will, of course, be lost in such a process, but perhaps some intrinsic property concerning order may be retained. Even for the integers, inequalities can be tricky, and the article may serve as a useful exercise in their manipulation.},
