The rank of a number is its size relative to other values in a list. Number is the number whose rank you want to find. Ref is an array of, or a reference to, a list of numbers. Non-numeric values in ref are ignored. Order is a number specifying how to rank number.
Duplicate numbers receive the same rank.
