Bringing the math tools of Python to the command-line

Project description

Bringing the math tools of Python to the command-line

Doing math on the command-line is hard. Integer math can be done with BASH, but the only utility around for floating-point math is bc, and that can be confusing with its scale and precision. What if you want the power of Python’s math, perhaps programmatically? Enter: pmath.

Examples

Basic input:

$ pmath '3 + 4'
7
$ echo '3+4' | pmath
7
$ pmath <<< 3+4
7
$ pmath 'x=3;x+2'
5

You can set the output format with a -f switch:

$ pmath -f'.4f' 'pow(2000, 1/3)'
12.5992
$ pmath -f'.4f' 'sin(pi/2)'
1.0000

Enabling complex math operations is straightforward:

$ pmath -c 'exp(1j*pi).real'
-1.0
