Agnostic Calculator

A Python3 library that parses strings representing mathematical expressions. The Calculator takes a converter by which means you can specify numerical types other than regular base 10 numbers. There is one converter available: roman.

Using pip:

pip install agnostic-calculator

Manually:

git clone git@github.com:carawarner/calculator.git
cd calculator/calculator
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

How to run tests

This libary uses pytest, a powerful but lightweight testing tool for Python.

cd calculator
pytest

How to use

WARNING: Don't use agnostic-calculator in production. The calculator library calls Python's eval() on user input. It's not safe.

from calculator.calculator import Calculator
import calculator.converters.roman as converter

calculator = Calculator(converter)
result = calculator.evaluate(expression)
