CalcPy
Terminal programmer calculator and advanced math solver using Python, IPython and SymPy.
The missing tweaks for using Python as a calculator.
## 🖥 Usage
**[🚀 Try online](https://calcpy.duckdns.org)**
## 📦 Installation
```
pip install https://github.com/idanpa/calcpy/archive/main.zip
```
[Android installation](docs/android.md)
## ✨ Features
* Display both symbolic and numeric solutions
* Integers displayed as decimal, hex and binary
* Evaluation preview while typing
* Currency conversion `10USD` (`calcpy.base_currency='EUR'` to change base currency) (by [ECB](https://www.ecb.europa.eu/))
* `?` suffix provides some basic analysis of expression (similar to [WolframAlpha](https://www.wolframalpha.com/))
`((1,2),(3,4))?`, `x**2+1?`, `234?`
* Automatic symbolic variables, anything like `x` `y_1` is a sympy symbol
* Symbolic variables assumptions are uniform, `symbols(x, real=True)` would change all occurencase of `x` to be real
* Implicit multiplication (`2x`, `(x+1)(x-1)` are valid)
* Nested tuples are matrices `((1,2),(3,4))**2`
* All variables and functions are restored between sessions (delete using `del`)
* Datetime calculations `d"yesterday at 9 am" - d"1990-1-30 9:20"` (by [dateparser](https://github.com/scrapinghub/dateparser))
* Sizes `KB`, `MB`, `GB`, `TB` (e.g. `4MB-32KB`)
* Unit prefixes `G`, `M`, `k`, `m`, `u`, `n`, `p` (`4G/3.2n`, enable by `calcpy.units_prefixes=True`)
* Implicit lambda `f(a,b):=a**2+b**2`
* Latex input `diff($\frac{1,x}$)` (latex output with `latex(1/x)`)
* Copy to clipboard `copy(_)` would copy last result
* Custom user startup (for imports, etc.) `edit_user_startup()`
* Persistent configuration, see options with `calcpy?`
#### [SymPy](https://www.sympy.org)
* All the elementary (and non-elementry) math functions and constants - `ln`, `sin`, `e`, `pi` etc.
* Calculus, algebra, plotting - `diff`, `integrate`, `limit`, `Sum`, `solve`, `plot`, `plot_implicit` etc.
#### [IPython](https://ipython.org)
* Get last result with `_`, get specific cell `_12` (`Out[12]` works too)
* `func_name?` show docs for func_name
* `who`/`who_ls` see all defined variables
* Prompt history with `up`/`down`, search with `ctrl+r`
* Autocomplete with `tab`
* Edit code on editor with `%edit func_name`
#### [Python](https://www.python.org/)
* All the basic arithmetic `+`,`-`,`*`,`/`,`**` or `^`
* Binary and hex input `0b1101`, `0xafe1`
* Scientific notation `2.12e-6`
* Programmer operations `//` integer division, `%` modulo, `&` bitwise AND, `|` bitwise OR, `^^` bitwise XOR (on calcpy `^` is exponentiation, disable with `calcpy.caret_power`), `~` bitwise not, `>>`/`<<` right/left shift.
