Trait float_cmp::ApproxOrd [−] [src]

pub trait ApproxOrd: ApproxEq + Ulps {
    fn approx_cmp(&self, other: &Self, ulps: Self::U) -> Ordering;

    fn approx_lt(&self, other: &Self, ulps: Self::U) -> bool { ... }

ApproxOrd is for sorting floating point values where approximate equality is considered equal.

Required Methods

fn approx_cmp(&self, other: &Self, ulps: Self::U) -> Ordering

This method returns an ordering between self and other values if one exists, where Equal is returned if they are approximately equal within ulps floating point representations. See module documentation for an understanding of ulps

Provided Methods

fn approx_lt(&self, other: &Self, ulps: Self::U) -> bool

This method tests less than (for self < other), where values within ulps of each other are not less than. See module documentation for an understanding of ulps.

fn approx_le(&self, other: &Self, ulps: Self::U) -> bool

This method tests less than or equal to (for self <= other) where values within ulps are equal. See module documentation for an understanding of ulps.

fn approx_gt(&self, other: &Self, ulps: Self::U) -> bool

This method tests greater than (for self > other) where values within ulps are not greater than. See module documentation for an understanding of ulps

fn approx_ge(&self, other: &Self, ulps: Self::U) -> bool

This method tests greater than or equal to (for self > other) where values within ulps are equal. See module documentation for an understanding of ulps.
