/**
* Implementation of 'the Excel function PERCENTRANK()
*
* <b>Syntax</b>:<br>
* <b>PERCENTRANK</b>(<b>array</b>, <b>X</b>, <b>[significance]</b>)<p>
*
* <b>array</b> The array or range of data with numeric values that defines relative standing.<br>
* <b>X</b> The value for which you want to know the rank.<br>
* <b>significance</b> Optional. A value that identifies the number of significant digits for the returned percentage value.
* If omitted, PERCENTRANK uses three digits (0.xxx).<br>
* <br>
* Returns a number between 0 and 1 representing a percentage.
*
* @since POI 5.1.0
