Implementations

impl<T> Ratio<T>

These method are const.

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

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

There are several methods that will panic if used on a Ratio with denom == 0.

pub fn into_raw(self) -> (T, T)

Deconstructs a Ratio into its numerator and denominator.

pub const fn numer(&self) -> &T

Gets an immutable reference to the numerator.

pub const fn denom(&self) -> &T

Gets an immutable reference to the denominator.

impl<T> Ratio<T>

where T: Clone + Integer,

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

Creates a new Ratio.

Panics if denom is zero.

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

Creates a Ratio representing the integer t.

pub fn to_integer(&self) -> T

Converts to an integer, rounding towards zero.

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.

Panics if denom is zero.

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

Returns the reciprocal.

Panics 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().

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

where &'a T: for<'a> Pow<u32, Output = T>,

Raises the Ratio to the power of an exponent.
