Struct Ratio 

pub struct Ratio {
    pub num: BigInt,
    pub den: BigInt,
}

Fields

num: BigInt

den: BigInt

Implementations

impl Ratio

pub fn new(num: BigInt, den: BigInt) -> Option<Self>

pub fn from_bigint(num: BigInt) -> Self

fn reduce(&mut self)

fn gcd_abs(a: &[u8], b: &[u8]) -> BigInt

pub fn new_or_zero(num: BigInt, den: BigInt) -> Self

new が失敗 (分母ゼロ) した場合に panic せず 0 を返すフォールバック付き生成。 分母非ゼロは呼び出し側の不変条件であり、通常は new がそのまま成功する。

pub fn add(&self, other: &Self) -> Self

pub fn sub(&self, other: &Self) -> Self

pub fn mul(&self, other: &Self) -> Self

pub fn div(&self, other: &Self) -> Option<Self>

pub fn to_string(&self) -> String

pub fn to_f64(&self) -> f64

pub fn from_f64(val: f64) -> Option<Self>

Trait Implementations

impl Clone for Ratio

fn clone(&self) -> Ratio

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ratio

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

Formats the value using the given formatter.

impl Eq for Ratio

impl PartialEq for Ratio

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