Struct Fraction 

pub struct Fraction {
    pub numerator: i32,
    pub denominator: i32,
}

Fraction

A lossless data representation of a float. Very simple, lightweight and straight implementation.

You can do all normal operations like adding and subtracting, multiplication and division. You can compare them too.

Examples:

use mathio::Fraction;
 
let frac_1 = Fraction::new(2, 3);
let frac_2 = Fraction::new(3, 6);
 
assert_eq!(frac_1 + frac_2, Fraction::new(7, 6));
assert_eq!(frac_1 - frac_2, Fraction::new(1, 6));
assert_eq!(frac_1 * frac_2, Fraction::new(1, 3));
assert_eq!(frac_1 / frac_2, Fraction::new(4, 3));
assert_eq!(frac_1 >= frac_2, true);

Fields

numerator: i32

denominator: i32

Implementations

impl Fraction

pub fn new(num: i32, den: i32) -> Fraction

Creates new fraction.

use mathio::Fraction;
 
let frac = Fraction::new(1, 2); // 1/2 or one_half

pub fn eval(&self) -> f32

Will evaluate the fraction and return a f32 approximation.

pub fn simplify(self) -> Fraction

Will check and simplify the fraction. Checks up to the first 100 prime numbers. If your fraction is a multiplication of a higher prime numbers, simplification will not work.

Trait Implementations

impl Add for Fraction

type Output = Fraction

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl AddAssign for Fraction

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Clone for Fraction

fn clone(&self) -> Fraction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fraction

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

Formats the value using the given formatter.

impl Default for Fraction

fn default() -> Fraction

Returns the “default value” for a type.

impl Display for Fraction

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

Formats the value using the given formatter.

impl Div for Fraction

type Output = Fraction

The resulting type after applying the / operator.

fn div(self, other: Self) -> Self

Performs the / operation.

impl DivAssign for Fraction

fn div_assign(&mut self, other: Self)

Performs the /= operation.

impl Mul for Fraction

type Output = Fraction

The resulting type after applying the * operator.

fn mul(self, other: Self) -> Self

Performs the * operation.

impl MulAssign for Fraction

fn mul_assign(&mut self, other: Self)

Performs the *= operation.

impl Ord for Fraction

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Fraction

fn eq(&self, other: &Self) -> 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 PartialOrd for Fraction

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for Fraction

type Output = Fraction

The resulting type after applying the - operator.

fn sub(self, other: Self) -> Self

Performs the - operation.

impl SubAssign for Fraction

fn sub_assign(&mut self, other: Self)

Performs the -= operation.

impl Copy for Fraction

impl Eq for Fraction
