ratioed

A Rational Number library for the Gleam programming language.

Quick start

The example below converts the floats 3/4 and 2/3 into rationals and multiplies them, giving a result of 1/2.

import gleam/io
import ratioed as r

pub fn main() {
  let a = r.from_f(3.0 /. 4.0)
  let b = r.from_f(2.0 /. 3.0)
  r.mul(a, b)
  |> r.to_string
  |> io.println
  // prints 1/2
}

Installation

If available on Hex this package can be added to your Gleam project:

gleam add ratioed

and its documentation can be found at https://hexdocs.pm/ratioed.
