Struct Rational 

pub struct Rational {
    pub num: i64,
    pub den: i64,
}

Fields

num: i64

den: i64

Implementations

impl Rational

pub const fn new(num: i64, den: i64) -> Self

pub const fn zero() -> Self

pub fn is_zero(&self) -> bool

pub fn as_f64(&self) -> f64

pub fn reduced(self) -> Self

Reduce the fraction to lowest terms. Sign is normalized onto the numerator.

pub fn invert(self) -> Self

Invert the fraction (num/den → den/num).

Trait Implementations

impl Clone for Rational

fn clone(&self) -> Rational

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rational

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

Formats the value using the given formatter.

impl Display for Rational

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

Formats the value using the given formatter.

impl Hash for Rational

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 Rational

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