[][src]Struct num_rational::Ratio

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

Represents the ratio between two numbers.

Methods

impl<T: Clone + Integer> Ratio<T>[src]

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

Creates a new Ratio. Fails if denom is zero.

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

Creates a Ratio representing the integer t.

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

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

pub fn to_integer(&self) -> T[src]

Converts to an integer, rounding towards zero.

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

Gets an immutable reference to the numerator.

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

Gets an immutable reference to the denominator.

pub fn is_integer(&self) -> bool[src]

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

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

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>[src]

Returns the reciprocal.

Fails if the Ratio is zero.

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

Rounds towards minus infinity.

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

Rounds towards plus infinity.

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

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

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

Rounds towards zero.

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

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>[src]

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

Raises the Ratio to the power of an exponent.

impl Ratio<BigInt>[src]

pub fn from_float<T: FloatCore>(f: T) -> Option<BigRational>[src]

Converts a float into a rational number.

impl<T: Integer + Signed + Bounded + NumCast + Clone> Ratio<T>[src]
