Equality comparisons based on floating point tolerances.
Required Associated Types§
Required Methods§
sourcefn default_epsilon() -> Self::Epsilon
fn default_epsilon() -> Self::Epsilon
The default tolerance to use when testing values that are close together.
This is used when no epsilon value is supplied to the relative_eq or ulps_eq macros.
sourcefn default_max_relative() -> Self::Epsilon
fn default_max_relative() -> Self::Epsilon
The default relative tolerance for testing values that are far-apart.
This is used when no max_relative value is supplied to the relative_eq macro.
sourcefn default_max_ulps() -> u32
fn default_max_ulps() -> u32
The default ULPs to tolerate when testing values that are far-apart.
This is used when no max_relative value is supplied to the relative_eq macro.
