Represents the ratio between two numbers.

Methods

impl<T: Clone + Integer> Ratio<T>

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

Creates a new Ratio. Fails if denom is zero.

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

Creates a Ratio representing the integer t.

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

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

pub fn to_integer(&self) -> T

Converts to an integer, rounding towards zero.

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

Gets an immutable reference to the numerator.

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

Gets an immutable reference to the denominator.

pub fn is_integer(&self) -> bool

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

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

Returns a reduced copy of self.

In general, it is not necessary to use this method, as the only method of procuring a non-reduced fraction is through new_raw.

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

Returns the reciprocal.

Fails if the Ratio is zero.

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

Rounds towards minus infinity.

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

Rounds towards plus infinity.

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

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

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

Rounds towards zero.

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

Returns the fractional part of a number, with division rounded towards zero.

Satisfies self == self.trunc() + self.fract().

impl<T: Clone + Integer + Pow<u32, Output = T>> Ratio<T>

pub fn pow(&self, expon: i32) -> Ratio<T>

Raises the Ratio to the power of an exponent.
