calcu

A simple calculator for your CLI.

(It uses Python's eval() and spits out the result, with some prettifying.)

Installation

pip install calcu

Usage

Type c followed by your expression.

Example:

c 2+2
             = 4

Refer to the result of the previous calculation with an underscore _:

c _+10
             = 14

Do multiplication and exponentiation:

c 2 x 3^2
             = 18
# you can also use * and ** but then you must
# wrap your expression in quotes ' ' or bash will mess it up
# eg: c '2*3**2'

And dividing and brackets:

c [2+10]/10
             = 1.2
# as above, the square brackets are to stop bash cleverness
# if you want to use regular brackets, use quotes
# eg: c '(2+10)/10

Use any function from Python's math library:

c log[e] x pi
             = 3.141592654

It returns the appropriate number of decimal values, up to 9.
