It is what is NOT in the Oberon report that should prevent you from making invalid assumptions. If rounding was involved the type of rounding would also need to be stated. e.g. towards zero, away from zero, banker’s rounding etc. etc. As it is not specified it can be deduced that any notion of involvement of rational numbers in the definition of DIV can be eliminated.
