Type Alias Quadratic 

pub type Quadratic = Poly<3>;

A polynomial of degree 2.

Aliased Type

pub struct Quadratic {
    pub(crate) coeffs: [f64; 3],
}

Fields

coeffs: [f64; 3]

Implementations

impl Quadratic

pub fn roots(&self) -> ArrayVec<f64, 2>

Returns the roots of this quadratic, in increasing order.

Double-roots are only counted once.

pub fn positive_discriminant_roots(&self) -> Option<(f64, f64)>

Returns the two distinct roots of this quadratic, but only if the discriminant is positive.

fn positive_discriminant_roots_scaled(&self) -> Option<(f64, f64)>
