source · [−]
pub struct Fraction {
    pub numerator: i128,
    pub denominator: i128,
}
Expand description

A struct to replace floats

Examples

use lemonmath::fraction::Fraction;
 
let x = Fraction::from_float(10.2082);
 
println!("{}", x);

Fields

numerator: i128denominator: i128

Implementations

This creates a new Fraction from a numerator and denominator.

Examples
use lemonmath::fraction::Fraction;
let x = Fraction::new(1, 2);
 
assert_eq!(x.numerator, 1);
assert_eq!(x.denominator, 2);

This creates a new Fraction from a float

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::from_float(1.0);
 
assert_eq!(x.numerator, 1);
assert_eq!(x.denominator, 1);

This adds two fractions together

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x.add_number(y), Fraction::new(7, 6));

This multiplies two fractions together

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x.mul_number(y), Fraction::new(1, 3));

This divides two fractions

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x.div_number(y), Fraction::new(3, 4));

This subtracts two fractions

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x.sub_number(y), Fraction::new(-1, 6));

This reduces the fraction to its lowest terms

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(2, 4);
 
assert_eq!(x.reduce(), Fraction::new(1, 2));

Trait Implementations

This adds two fractions together

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x + y, Fraction::new(7, 6));

The resulting type after applying the + operator.

This adds two fractions together and then assigns the result to the original fraction

Examples
use lemonmath::fraction::Fraction;
 
let mut x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
x += y;
assert_eq!(x, Fraction::new(7, 6));

This returns a fraction with a numerator of 0 and a denominator of 1

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::default();
 
assert_eq!(x, Fraction::new(0, 1));

This displays the fraction as a string

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
 
assert_eq!(format!("{}", x), "1/2");

This divides two fractions

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x / y, Fraction::new(3, 4));

The resulting type after applying the / operator.

This divides two fractions and then assigns the result to the original fraction

Examples
use lemonmath::fraction::Fraction;
 
let mut x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
x /= y;
assert_eq!(x, Fraction::new(3, 4));

This multiplies two fractions together

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x * y, Fraction::new(1, 3));

The resulting type after applying the * operator.

This multiplies two fractions and then assigns the result to the original fraction

Examples
use lemonmath::fraction::Fraction;
     
let mut x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
x *= y;
assert_eq!(x, Fraction::new(1, 3));

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=.

This subtracts two fractions

Examples
use lemonmath::fraction::Fraction;
 
let x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
assert_eq!(x - y, Fraction::new(-1, 6));

The resulting type after applying the - operator.

This subtracts two fractions and then assigns the result to the original fraction

Examples
use lemonmath::fraction::Fraction;
 
let mut x = Fraction::new(1, 2);
let y = Fraction::new(2, 3);
 
x -= y;
assert_eq!(x, Fraction::new(-1, 6));
