A simple calculator library.

Project Description
Calculator
==========

A simple calculator library.

This module is now a Python package. You can install it using:

$ sudo pip install simplecalculator

Examples of usage:

* `simplecalculator.py` -- a command-line utility

* `tornadoweb.py` -- a TornadoWeb applications with a minimalistic RESTful API. Do you math with curl!

How?
----

Clone this repo and tests:

$ python -m unittest test

All good?

Usage (in your script)
-----------------------

1. Import `calculator`

2. Instantiate `SimpleCalculator()`

3. Call `run()` with the list of values, operands, and functions you want to process.

4. The history of operations, results, and unprocessed input is stored in `SimpleCalculator.log`.

Here's a short sample:

from calculator.simple import SimpleCalculator

c = SimpleCalculator()
c.run('1 + 1')
print c.log

If you want to read the state of the LCD (no kidding!), use

print c.lcd

Usage (on the command line)
---------------------------

Run:

$ ./simplecalculator.py -s "1 + 2 / 6 acv 1 + 1 / 33 fmod 0.01"

then


$ ./simplecalculator.py -s "1 + 2 / 6 acv 1 + 1 / 33 ceil fmod"

then

$ ./simplecalculator.py -s "1 + 2 / 6 acv 1 + 1 / 33 fmod 0.01 1 2 3 4"

This calculator is as forgiving as a simple desktop calculator, it will ignore what it does not know, try to compute what it can treating the given string as a list of keystrokes. You may see one or more `status` entries after the last result, that's intended.

Usage (via curl)
----------------

If you want to implement this alculator as a RESTful API, install [TornadoWeb](http://tornadoweb.org 'TornadoWeb') and run `tornadoweb.py', then use curl:

$ curl -X POST http://localhost:8888/v1/calculate -d '1 + 2 / 6 acv 1 + 1 / 33 fmod 0.01 1 2 3 4'

You can easily extend this calculator to support any number of one- and two-argument functions, search calculator/simple.py for `fmod` and `ceil` to see what modifications you need to make.

Why?
----

I got asked to provide samples of my work, proof I know Python, etc. This project is way more than what I was asked to deliver, but I had more time to spare. There is more coming.
