CalcPy

Terminal calculator and advanced math solver using Python, IPython and SymPy.

Usage

Prerequisites - Python

pip install git+https://github.com/idanpa/calcpy

(no git? use pip install https://github.com/idanpa/calcpy/archive/main.zip)
Android installation

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)
? suffix provides some basic analysis of expression (similar to WolframAlpha)
((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)
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?

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.

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.
