Struct num::rational::RatioExperimental

pub struct Ratio<T> {
    // some fields omitted
}

Represents the ratio between 2 numbers.

Methods

impl<T: Clone + Integer + PartialOrd> Ratio<T>

fn from_integer(t: T) -> Ratio<T>

Creates a ratio representing the integer t.

fn new_raw(numer: T, denom: T) -> Ratio<T>

Creates a ratio without checking for denom == 0 or reducing.

fn new(numer: T, denom: T) -> Ratio<T>

Create a new Ratio. Fails if denom == 0.

fn to_integer(&self) -> T

Converts to an integer.

fn numer<'a>(&'a self) -> &'a T

Gets an immutable reference to the numerator.

fn denom<'a>(&'a self) -> &'a T

Gets an immutable reference to the denominator.

fn is_integer(&self) -> bool

Returns true if the rational number is an integer (denominator is 1).

fn reduced(&self) -> Ratio<T>

Returns a reduced copy of self.

fn recip(&self) -> Ratio<T>

Returns the reciprocal.

fn floor(&self) -> Ratio<T>

Rounds towards minus infinity.

fn ceil(&self) -> Ratio<T>

Rounds towards plus infinity.

fn round(&self) -> Ratio<T>

Rounds to the nearest integer. Rounds half-way cases away from zero.

fn trunc(&self) -> Ratio<T>

Rounds towards zero.

fn fract(&self) -> Ratio<T>

Returns the fractional part of a number.

impl Ratio<BigInt>

fn from_float<T: Float>(f: T) -> Option<BigRational>

Converts a float into a rational number.
