Struct uncertainty::unc::Unc

pub struct Unc;

A fieldless struct only used to instantiate AbUnc and RelUnc values.

Methods

impl Unc

pub fn ab(val: f64, unc: f64) -> AbUnc

Create an absolute uncertainty. The first parameter is the base value, and the second parameter is the absolute uncertainty in that value.

Examples

use uncertainty::*;

let u: AbUnc = Unc::ab(10.0, 1.0);
assert_eq!(u.val(), 10.0);
assert_eq!(u.unc(), 1.0);

pub fn rel(val: f64, unc: f64) -> RelUnc

Create a relative uncertainty. The first parameter is the base value, and the second parameter is the relative uncertainty in the value, expressed as a decimal fraction.

Examples

use uncertainty::*;

let u: RelUnc = Unc::rel(10.0, 0.1);
assert_eq!(u.val(), 10.0);
assert_eq!(u.unc(), 0.1);
