ab: 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.
