Expand description

Enum representing the different methods used when rounding a number.

Variants

`Round05Up`

Round away from zero if last digit after rounding towards zero would have been 0 or 5; otherwise round towards zero.

`RoundCeiling`

Round towards Infinity.

`RoundDown`

Round towards zero.

`RoundFloor`

Round towards -Infinity.

`RoundHalfDown`

Round to nearest with ties going towards zero.

`RoundHalfEven`

Round to nearest with ties going to nearest even integer.

`RoundHalfUp`

Round to nearest with ties going away from zero.

`RoundUp`

Round away from zero.

Implementations

source

impl RoundingMode

source

pub fn set_default(mode: RoundingMode)

Sets the default RoundingMode for the current thread.

Trait Implementations

source

impl Clone for RoundingMode

source

fn clone(&self) -> RoundingMode

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for RoundingMode

source

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

Formats the value using the given formatter. Read more

source

impl Default for RoundingMode

source

fn default() -> Self

Returns the default RoundingMode set for the current thread.

It is initially set to RoundingMode::RoundHalfEven, but can be changed using the fn RoundingMode::set_default.

source

impl PartialEq<RoundingMode> for RoundingMode

source

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

This method tests for self and other values to be equal, and is used by ==. Read more

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

This method tests for !=.

U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.
