Trait statrs::statistics::Max

pub trait Max<T> {
    fn max(&self) -> T;
}

The Max trait specifies that an object has a maximum value

Required methods

fn max(&self) -> T

Returns the maximum value in the domain of a given distribution representable by a double-precision float. May panic depending on the implementor.

Examples

use statrs::statistics::Max;
use statrs::distribution::Uniform;

let n = Uniform::new(0.0, 1.0).unwrap();
assert_eq!(1.0, n.max());

Implementations on Foreign Types

impl Max<f64> for [f64]

fn max(&self) -> f64

Returns the maximum value in the data

Remarks

Returns f64::NAN if data is empty or an entry is f64::NAN

Examples

use std::f64;
use statrs::statistics::Max;

let x: [f64; 0] = [];
assert!(x.max().is_nan());

let y = [0.0, f64::NAN, 3.0, -2.0];
assert!(y.max().is_nan());

let z = [0.0, 3.0, -2.0];
assert_eq!(z.max(), 3.0);
