Function percentile 

Source 
pub fn percentile<T>(collection: &[T], p: f64) -> Option<f64>
where
    T: Copy + Into<f64> + PartialOrd,
Expand description

Calculates the specified percentile of a collection. The percentile should be a value between 0 and 100. The collection will be sorted before calculation. Uses linear interpolation between closest ranks for non-integer results.

§Arguments

  • collection - A slice of items to calculate the percentile from
  • p - The percentile to calculate (0-100)

§Returns

  • Option<f64> - The calculated percentile value, or None if the collection is empty

§Examples

use lowdash::percentile;
let numbers = vec![1, 2, 3, 4, 5];
let result = percentile(&numbers, 50.0);
assert!((result.unwrap() - 3.0).abs() < f64::EPSILON);
use lowdash::percentile;
let numbers = vec![1, 2, 3, 4];
let result = percentile(&numbers, 75.0);
assert!((result.unwrap() - 3.25).abs() < f64::EPSILON);
