ARGON 3 is a math-driven programming language designed to make code easy to read and write. It's not meant to be fast, as it's interpreted. This specification should be used as a guideline, and is subject to change for later versions. Later updates for Argon 3 should be backwards compatible (where possible) with code designed for older versions of the interpreter.
## 📚 Features
- Easy to read and write: Argon 3 is designed with clarity of code in mind, making it easier for you and others to read and write code.
- All numbers are stored as rational numbers, preventing precision errors.
- Math-driven: Designed for mathematical computations, Argon 3 uses techniques and rules set in maths. It's designed to be easy for mathematicians to write and understand algorithms in.

As of now, Argon 3 does not have an installer. Feel free to clone this repo and run the `build` file for your plateform. the build will be found in `bin/argon(.exe)`.
## 📖 Usage
To use Argon 3, you can create a file with the .ar extension and write your code in it. Then, you can run your code using the interpreter. For example, if you have a file called example.ar, you can run it using the following command:
