The MEDIAN Function

Returned Values

1. The returned value is the content of the argument-1 having the middle value in the list formed by arranging all the argument-1 values in sorted order.
2. If the number of occurrences referenced by argument-1 is odd, the returned value is such that at least half of the occurrences referenced by argument-1 are greater than or equal to the returned value and at least half are less than or equal. If the number of occurrences referenced by argument-1 is even, the returned value is the arithmetic mean of the values referenced by the two middle occurrences.
3. The comparisons used to arrange the argument-1 values in sorted order are made according to the rules for relation conditions. See the topic Relation Condition in the chapter Procedure Division.
4. Floating-point format is used for numeric non-integer results.
