Function median 

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

Calculate the median value of a collection. The median is the 50th percentile of a collection. For collections with an even number of elements, the median is the average of the two middle values. The collection will be sorted before calculation.

§Arguments

  • collection - A slice of items to calculate the median from

§Returns

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

§Examples

use lowdash::median;
let numbers = vec![1, 3, 5, 2, 4];
let result = median(&numbers);
assert!((result.unwrap() - 3.0).abs() < f64::EPSILON);
use lowdash::median;
let numbers = vec![1, 2, 3, 4];
let result = median(&numbers);
assert!((result.unwrap() - 2.5).abs() < f64::EPSILON);
