Instant calculating from the terminal into the terminal

---

bashcalc is an instant command-line tool for calculating directly mathematical expression into the terminal.

It is designed for working on cluster-server, where numbers or expressions have to be calculated without starting a new application or blogging any terminal windows. Therefore it will just show the result and immediately close. For this purpose, it is a pure python based and does not require any additional packages.

The idea is to have a simplistic tool that can quickly plot the results to the screen with various options:

1. simple example

╰─ bashcalc 1230/2
>>> 615

2. advanced example

╰─ pipenv run bashcalc "2*exp(3+(2//3))"
>>> 40.1710738463753358473695698194205760955810546875

3. advanced example with rounded output

╰─ pipenv run bashcalc "2*exp(3+(2//3))" -r 5
>>> 40.17107

4. advanced example as scientific output

╰─ pipenv run bashcalc "2*exp(3+(2//3))" -s 5 -b
>>> 4.01711E+1

                infile

copy or rename any file(s) to a hash-secured filename via terminal

positional arguments:
  infile                Write the mathematic expression like: "(2 + 4) * 3"

optional arguments:
  -h, --help            show this help message and exit
  -c COLOR, --color COLOR
                        define the color of the output. The following options

  -i, --int             Result will be printed as intiger-value
  -r ROUND, --round ROUND
                        Result will be printed as rounded float-value for
                        given number of digits
  -s SCIENCE, --science SCIENCE
                        Result will be printed in scientific notation
  -v, --version         displays the current version of bashcalc
