Returns the rank of a number in a list of numbers. The rank of a number is its size relative to other values in a list. Syntax: RANK(number,ref,order) Number is the number whose rank you want to find. Ref is an array of, or a reference to, a list of numbers. Nonnumeric values in ref are ignored. Order is a number specifying how to rank number. If order is 0 (zero) or omitted, Microsoft Excel ranks number as if ref were a list sorted in descending order. If order is any nonzero value, Microsoft Excel ranks number as if ref were a list sorted in ascending order.
