# Struct num_rational::Ratio
[−]
[src]

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

Represents the ratio between 2 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 + PrimInt> Ratio<T>`

[src]

`impl Ratio<BigInt>`
