I made a rational object for javascript

In plain words

Ratio.js is a JavaScript library that implements rational number arithmetic. It enables developers to perform precise calculations using fractions rather than floating-point numbers, avoiding common precision errors. The tool is designed for programmers who need accurate mathematical computations in JavaScript applications. It is open-source and available on GitHub for community contributions and development.
