Struct ArbitraryRational 

pub struct ArbitraryRational { /* private fields */ }

Arbitrary precision rational number

Implementations

impl ArbitraryRational

pub fn new() -> Self

Create a new rational number (0/1)

pub fn num(num: i64, den: i64) -> CoreResult<Self>

Create from numerator and denominator

pub fn num_2(num: &ArbitraryInt, den: &ArbitraryInt) -> CoreResult<Self>

Create from arbitrary precision integers

pub fn parse_rational(s: &str) -> CoreResult<Self>

👎Deprecated: Use str::parse() instead

Create from string (e.g., “22/7” or “3.14159”)
Note: This is deprecated, use str::parse() instead

pub fn to_f64(&self) -> f64

Convert to f64 (may lose precision)

pub fn to_arbitrary_float(&self, prec: u32) -> CoreResult<ArbitraryFloat>

Convert to arbitrary precision float

pub fn numerator(&self) -> ArbitraryInt

Get numerator

pub fn denominator(&self) -> ArbitraryInt

Get denominator

pub fn abs(&self) -> Self

Get the absolute value

pub fn recip(&self) -> CoreResult<Self>

Get the reciprocal

Trait Implementations

impl Add for ArbitraryRational

type Output = ArbitraryRational

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for ArbitraryRational

fn clone(&self) -> ArbitraryRational

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArbitraryRational

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ArbitraryRational

fn default() -> Self

Returns the “default value” for a type.

impl Display for ArbitraryRational

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Div for ArbitraryRational

type Output = ArbitraryRational

The resulting type after applying the / operator.

fn div(self, rhs: Self) -> Self::Output

Performs the / operation.

impl FromStr for ArbitraryRational

type Err = CoreError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Mul for ArbitraryRational

type Output = ArbitraryRational

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl Neg for ArbitraryRational

type Output = ArbitraryRational

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for ArbitraryRational

fn eq(&self, other: &ArbitraryRational) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub for ArbitraryRational

type Output = ArbitraryRational

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Eq for ArbitraryRational
