Enum RoundingMode

Rounding modes for floating-point numbers.

For many floating-point operations, infinitely precise results may not be representable with the number of available bits. Thus, the results are rounded in a certain way to one of the representable floating-point numbers.

\verbatim embed:rst:leading-asterisk These rounding modes directly follow the SMT-LIB theory for floating-point arithmetic, which in turn is based on IEEE Standard 754 :cite:IEEE754. The rounding modes are specified in Sections 4.3.1 and 4.3.2 of the IEEE Standard 754. \endverbatim

Trait Implementations

impl Clone for RoundingMode

fn clone(&self) -> RoundingMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoundingMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for RoundingMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RoundingMode

fn eq(&self, other: &RoundingMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
