Trait Implementations§

impl ApproxEq for NormalizedF64

§

type Margin = F64Margin

This type type defines a margin within which two values are to be considered approximately equal. It must implement Default so that approx_eq() can be called on unknown types.
source§

fn approx_eq<M: Into<Self::Margin>>(self, other: Self, margin: M) -> bool

This method tests that the self and other values are equal within margin of each other.
source§

fn approx_ne<M>(self, other: Self, margin: M) -> bool
where M: Into<Self::Margin>,

This method tests that the self and other values are not within margin of each other.
source§

impl ApproxEqUlps for NormalizedF64

§

type Flt = f64

source§

fn approx_eq_ulps(&self, other: &Self, ulps: i64) -> bool

This method tests for self and other values to be approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.
source§

fn approx_ne_ulps(&self, other: &Self, ulps: <Self::Flt as Ulps>::U) -> bool

This method tests for self and other values to be not approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.
