CalcPy – terminal calculator and advanced math solver

CalcPy is a terminal calculator and advanced math solver using Python, IPython and SymPy.

This is free and open source software.

Key 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).
• ? 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″.
• 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:
  • 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:
  • 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:
  • 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.
