Trait approx::UlpsEq [−][src]
pub trait UlpsEq<Rhs = Self>: AbsDiffEq<Rhs> where
Rhs: ?Sized, { fn default_max_ulps() -> u32; fn ulps_eq(
&self,
other: &Rhs,
epsilon: Self::Epsilon,
max_ulps: u32
) -> bool; fn ulps_ne(
&self,
other: &Rhs,
epsilon: Self::Epsilon,
max_ulps: u32
) -> bool { ... } }
Equality comparisons between two numbers using both the absolute difference and ULPs (Units in Last Place) based comparisons.
Required methods
fn default_max_ulps() -> u32
[src]
The default ULPs to tolerate when testing values that are far-apart.
This is used when no max_ulps
value is supplied to the ulps_eq
macro.
fn ulps_eq(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool
[src]
A test for equality that uses units in the last place (ULP) if the values are far apart.
Provided methods
fn ulps_ne(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool
[src]
The inverse of UlpsEq::ulps_eq
.
