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 with -c:

$ pmath -c <<< exp(1j*pi).real
-1.0
$ pmath -f.2f -c 'ang=3*pi/4; exp(1j*ang)'
-0.71+0.71j

Installation

Running pip install pmath will install the command-line utility.
