PERCENTRANK (Array,Number,Significance)

is the set of data and is the value to find the rank.
- PERCENTRANK(),returns the percentage rank of a value in a data set.

This function gives the percentage rank of a value in a given set of numbers.
To calculate the relative standing of a data set we can use this function.
For example, a test score that is greater than or equal to 50% of the scores of people taking the test is said to be at the 50th percentile rank.
Percentile ranks are commonly used to clarify the interpretation of scores on standardized tests.
To find the percentile rank of a score is : $PR\%={\frac {L+(0.5*S)}{N}}$

Where, $L$ = Number of below rank, $S$ = Number of same rank, $N$ = Total numbers.

In $PERCENTRANK(Array,Number,Significance)$ , $Array$ is the array of numeric values and $Number$ is the value to find the rank.
This function gives the result as error when array is empty .
