Project description
cli-calc
Powerful yet easy command line calculator.
Example Usage
cos(pi/2)
0xFF ^ 0b10
2**8-1
log(2)
comb(49,6)
factorial(42)
random()
cmath.phase(complex(-1.0, 0.0))
All function of the following Math Libraries are ready to use out of the box
-
standard operators
-, >>, ... -
standard math library
cd, log, sin, sinh, gamma, pi, e, tau, inf, nan... -
cmath
phase(complex(-1.0, 0.0)), and then most of the above with complex numbers. -
random
random, choice(['win', 'lose', 'draw']), mean, ... -
built in functions
max, help, sum, ...
Installation
pip install cli-calc
Configuration
In order to run it from anywhere: Add a symbolic link in ~/bin
cd ~/bin
ln -s ~/path/to/your/install/cli_calc/warpper.sh calc
Then use it anywhere. :-)
calc
echo "7+8" | calc
cat foo.bar | calc
Help
calc
h
Input:
"q" for quit, "h" for help
"_float_" and/or "_int_" for last value
"pi", "tau" and "e" for pi, tau and Euler
"+f" to add display for fraction, "-f" to suppress display for fraction
Other letters are:
he(x), (o)ctal, (b)inary, (i)nteger,
(f)raction, (t)ruth, i(e)ee, ieee_bi(n), f(r)om_ieee
"float" is always visible
See https://docs.python.org/3/library/math.html, use without "math."
https://www.w3schools.com/python/python_operators.asp
Try "cos(pi/2)", XOR: "0xFF ^ 0b10", "2**8-1", "factorial(42)",
"help(math)"
Warning
- Use of
evalis evil. However some precautions are taken.
