# 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]

#### `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: Float>(f: T) -> Option<BigRational>`
[src]

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
