/** | |||||
* 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. | |||||
