Equator

A maths interpreter built in Python using SymPy

Features:

• Solve simultaneous equations
• Simplify expressions
• It can do maths faster than you

Installation

Equator can be installed from PyPi. Run the command

pip3 install equatorpy

Usage:

Start-up:

Equator can be run directly through the Python module. Run the command

python3 -m equator

Alternatively, Equator can be invoked directly using the command

equator

The program has been tested on Windows and Linux (Ubuntu), but not MacOS. It might work, but it might not.

• If no arguments are provided, the program launches into a full interpreter, built using the Curses library.
• If it is started with the argument json, then its output will be in a JSON format, where each line of input is treated as one set of equations and expressions. Each input will have one line of respective output, in JSON format.
• If it is started with the argument ev, then it will run a quick evaluation on the following argument. For example equator ev "1 + 1" would print 2.

Syntax:

• Order of operations is respected (including brackets)
• Use standard mathematical syntax (+, -, *, /, ^, =, etc)
• Functional notation is used for unary operators:
  • |A| should be written as abs(A)
• Equations or expressions are separated by semicolons

Development

When working with Equator, it is recommended to work with a virtual environment.

After git cloneing the repository, set up a virtual environment using these instructions, then install the required dependencies using the command

pip3 install -r requirements.txt

or if you're on Windows

pip install -r requirements_windows.txt

You should then be able to debug or develop the interpreter normally.
