Methods

impl Ratio

fn zero() -> Ratio

Returns a Ratio with the value 0.

fn new(numerator: i128, denominator: i128) -> Self

Constructs a new Ratio.

Panics

• denominator is zero

Returns the numerator part of this ratio.

fn denominator(&self) -> i128

Returns the denominator part of this ratio.

fn percentage(&self, precision: usize) -> String

Returns a string representing this ratio as a percentage.

fn real(&self, precision: usize) -> String

Returns a string representing this ratio as a real number.

fn checked_add(&self, other: Ratio) -> Option<Ratio>

Returns the sum of this ratio and the supplied ratio unless overflow occurs.

fn checked_div(&self, other: Ratio) -> Option<Ratio>

Returns the quotient of this ratio and the supplied ratio unless overflow occurs.

fn checked_mul(&self, other: Ratio) -> Option<Ratio>

Returns the product of this ratio and the supplied ratio unless overflow occurs.

fn checked_sub(&self, other: Ratio) -> Option<Ratio>

Returns the difference of this ratio and the supplied ratio unless overflow occurs.
