Rational Math Calculator

RatCalc is a rational math calculator for Elixir. It is a stand-alone library whose goal is to implement a real-number arithmetic based on rational intervals as replacements for decimals. See Reals as Oracles for the mathematical background for this idea.

Essentially, this implements an arithmetic of fractions which then, when coupled with rational interval representation of real numbers, becomes a real number calculator.

Installation
