Struct Rounding 

pub(super) struct Rounding<const N: usize> {
    pub(super) value: f64,
    pub(super) derivative: [f64; N],
}

First-order bounds on the absolute rounding errors of a jet’s value and of each of its derivatives, in units of epsilon.

Fields

value: f64

derivative: [f64; N]

Implementations

impl<const N: usize> Rounding<N>

pub(super) const fn of(value: f64) -> Self

A bound on a value only, whose derivatives are exact.

pub(super) fn times(self, exact: &Jet<N>) -> Self

The bounds of exact * inexact, where self bounds inexact. Bounds take the cheaper |Re| + |Im| for moduli, at most sqrt 2 larger.

pub(super) fn relative(jet: &Jet<N>, factor: f64) -> Self

The moduli of a jet’s value and derivatives times factor: a bound for a jet computed with a relative error of factor ulps in each component.

fn turned(self, phase: &Jet<N>) -> Self

The bounds of phase * inexact for a phase of modulus 1, where self bounds inexact: its value keeps its bound, which the derivatives of the phase carry into theirs.

pub(super) fn max(self, other: Self) -> Self

The larger bound of each component.
