Struct PolynomialRoot

pub struct PolynomialRoot {
    pub x: f64,
    pub lower: f64,
    pub upper: f64,
    pub kind: RootKind,
}

A real root, or an unresolved root region, of a polynomial.

Fields

x: f64

Best estimate.

lower: f64

Lower end of the enclosure.

upper: f64

Upper end of the enclosure. |x - root| <= upper - lower for every root the entry accounts for.

kind: RootKind

Whether the entry is one certified simple root.

Implementations

impl PolynomialRoot

pub fn error_bound(&self) -> f64

A bound on the distance from x to each root this entry accounts for: the enclosure width.

Trait Implementations

impl Clone for PolynomialRoot

fn clone(&self) -> PolynomialRoot

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PolynomialRoot

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PolynomialRoot

fn eq(&self, other: &PolynomialRoot) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
