Enum Rounding 

pub enum Rounding {
    HalfEven,
    HalfUp,
    HalfDown,
    Down,
    Up,
}

Rounding represents the different strategies that can be used.

Rounding::HalfEven - Rounds toward the nearest even number, e.g. 5.5 -> 6, 4.5 -> 4 Rounding::HalfUp - Rounds up if the value >= 5, otherwise rounds down, e.g. 6.5 -> 7 (default), Rounding::HalfDown - Rounds down if the value =< 5, otherwise rounds up, e.g. 4.5 -> 4, 4.51 -> 5, 1.4999 -> 1 Rounding::Down - Always round down. Rounding::Up - Always round up.

Variants

HalfEven

Rounds toward the nearest even number, e.g. 5.5 -> 6, 4.5 -> 4

HalfUp

Rounds up if the value >= 5, otherwise rounds down, e.g. 6.5 -> 7 (default)

HalfDown

Rounds down if the value <= 5, otherwise rounds up, e.g. 4.5 -> 4, 4.51 -> 5

Down

Always rounds down.

Up

Always rounds up.

Trait Implementations

impl Clone for Rounding

fn clone(&self) -> Rounding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for Rounding

fn eq(&self, other: &Rounding) -> 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.

impl Copy for Rounding

impl Eq for Rounding

impl StructuralPartialEq for Rounding
