rank

rank

Overview

The rank function operates on a collection of numerical values. It sorts them in descending order (by default) and returns the rank (order) of the requested element in that order.

Note:

  • The numerical values should be available inside a collection.
  • Invoking the rank function on values other than numbers or decimals will result in a runtime error.

Return Type

  • NUMBER / DECIMAL

Syntax

<variable>=<collection>.rank(<number>, [<sort_order>]);

where,

ParameterData typeDescription
<variable>NUMBERVariable which contains the rank of the requested element.
<numberCollection>COLLECTIONThe collection of numerical values.
<number>NUMBER / DECIMALThe numerical value for which the rank has to be determined.
<sort_order>

(optional)

TEXTThe rank is determined based on elements sorted in the descending order by default. This parameter is used to reverse the sorting order.

This parameter takes "asc" (case-insensitive) as a value.

Examples

 marks=Collection(300,455,124,926,780);
 order=marks.rank(300);// the variable order is assigned the value 4

 marks=Collection(120.12,65,300.46,600.25,80.5);
 order=marks.rank(80.5, "asc");// the variable order is assigned the value 2 as the elements are sorted in ascending order

 marks=Collection(120.12,65,300.46,600.25,80.5);
 order=marks.rank(100);// A run-time error ('List contains invalid(TEXT) entries hence' can not be cast to 'valid list and perform desired operations') will be thrown as there is no such element
