Implementations

impl Fraction

pub fn new(numerator: i64) -> Fraction

Generates a new Fraction

It returns a Fraction in its fully reduced form, after calculating the greatest common divisor.

pub fn new_denom(numerator: i64, denominator: i64) -> Fraction

Generates a new Fraction

It returns a Fraction in its fully reduced form, after calculating the greatest common divisor.

Panics

Panics if denominator is zero (0).

pub fn greatest_common_divisor(numerator: i64, denominator: i64) -> i64

Returns the greatest common divisor, as an i64.

Examples

let n1 = 50;
let n2 = 20;

// Prints out "10"
println!("{}", Fraction::greatest_common_divisor(n1, n2));

pub fn reciprocal(self) -> Fraction

Returns the reciprocal of the Fraction it’s called on.

Just moves the denominator to the numerator position and vice versa.

Panics

Panics when being called on a Fraction with numerator 0.

pub fn sqrt(&self) -> Fraction

Returns the square-root of a Fraction. Result is a Fraction

pub fn cosine(self) -> Fraction

Returns an approximated Fraction of the cosine (cos) of the Fraction

pub fn arc_cosine(self) -> Fraction

Returns an approximated Fraction of the arc cosine (cos^-1) of the Fraction

pub fn sine(self) -> Fraction

Returns an approximated Fraction of the sine (sin) of the Fraction

pub fn arc_sine(self) -> Fraction

Returns an approximated Fraction of the arc sine (sin^-1) of the Fraction

pub fn tangent(self) -> Fraction

Returns an approximated Fraction of the tangent (tan) of the Fraction

pub fn arc_tangent(self) -> Fraction

Returns an approximated Fraction of the arc tangent (tan^-1) of the Fraction
