## What is RCalc?

A Calculator for Rational Numbers

You can also explore the prime factors of numbers with prime factors not exceeding a certain (large) limit.

You can save your calculations as programs and open them later.

Its zoomable output display allows you to magnify its contents for easy viewing experience.
