What is num2fraction?

The num2fraction npm package is designed to convert decimal numbers to their simplest fractional representation. This can be particularly useful in applications that require displaying numbers in a more human-readable form, such as in cooking recipes or mathematical education tools.

What are num2fraction's main functionalities?

Decimal to Fraction Conversion

This feature allows you to convert a decimal number to its simplest fractional form. The code sample demonstrates converting the decimal numbers 0.5 and 1.75 to their fractional representations, '1/2' and '7/4' respectively.

const num2fraction = require('num2fraction');
console.log(num2fraction(0.5)); // Outputs: '1/2'
console.log(num2fraction(1.75)); // Outputs: '7/4'

Other packages similar to num2fraction

fraction.js

Fraction.js is a package that not only converts decimals to fractions but also provides a comprehensive set of operations for fractions, such as addition, subtraction, multiplication, and division. It offers more extensive functionality compared to num2fraction, which focuses solely on conversion.

Installation

npm install num2fraction

Usage

var π   = Math.PI
var n2f = require('num2fraction')
  console.log(n2f(0))               // => 0
  console.log(n2f(.2))              // => 1/5
  console.log(n2f(1.1))             // => 11/10
  console.log(n2f(1.2))             // => 6/5
  console.log(n2f(1.3))             // => 13/10
  console.log(n2f(1.4))             // => 7/5
  console.log(n2f(1.5))             // => 3/2
  console.log(n2f(2))               // => 2/1
  console.log(n2f(2.1))             // => 21/10
  console.log(n2f(3))               // => 3/1
  console.log(n2f(2.555))           // => 511/200
  console.log(n2f(8.36))            // => 209/25
  console.log(n2f('3em'))           // => 3/1
  console.log(n2f('1.5px'))         // => 3/2
  console.log(num2fraction(7 / 9)             // => 7/9
  console.log(num2fraction(8 / 9)             // => 8/9
  console.log(num2fraction(512 / 999)         // => 512/999
  console.log(num2fraction((2 * π / 3) / π)   // => 2/3
  console.log(num2fraction((8 * 5) / (4 / 2)) // => 20/1
