We could make things indeed more precise. Say for ceil, we use
"smallest *following* integer", and for floor, "largest *previous*
integer", and we keep the mention to "not less/greater than argument"
to show the fact that a numeric already rounded to an integer is equal
to itself. See the patch attached.
