Powerful yet easy command line calculator.
## Introduction
Please note: Using plain python at the command line already does provide a pretty decent calculator:
```
$ python
Python 3.8.5 (default, Aug 2 2020, 16:00:15)
[Clang 11.0.0 (clang-1100.0.33.17)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 2**10
1024
>>> _ / 10
102.4
>>> import math
>>> math.pi
3.141592653589793
>>> math.sin(math.pi / 2)
1.0
>>> exit()
```

[Python as a Calculator](https://docs.python.org/3/tutorial/introduction.html#using-python-as-a-calculator).
]
But not all is straight forward.
For example, if you want to calculate ```sin(pi/2)```:
* First you need to ```import math```,
* and then use it with ```math.sin( math.pi / 2 )```.
But
[there must be a better way!](https://www.youtube.com/watch?v=UANN2Eu6ZnM)
And there is...
### cli-calc
```
$ cli-calc
hex, int, float, : INPUT
0x0, 0, 0.0, : 2**10
2**10
0x400, 1024, 1024.0, : _ / 10
1024.0/10
0x66, 102, 102.4, : pi
pi
0x3, 3, 3.141592653589793, : sin(pi / 2)
sin(pi/2)
0x1, 1, 1.0, : q
$
```
[Batteries included](https://www.python.org/dev/peps/pep-0206/#batteries-included-philosophy):
* ```cli-calc``` adds the standard
[math](https://docs.python.org/3/library/math.html)
library to the mix, as well as cmath and others.
* Provides convenience functions for formatted output, like
[fractions](https://docs.python.org/3.6/library/fractions.html)
and
[IEEE 754](https://en.wikipedia.org/wiki/IEEE_754).
* Supports line input from files and Unix pipes.
* And some more... :-)

```
## Included Math Libraries
Ready to use out of the box:
- [standard operators](https://www.w3schools.com/python/python_operators.asp)
``` -, >>, ...```
- [standard math library](https://docs.python.org/3/library/math.html)
```cd, log, sin, sinh, gamma, pi, e, tau, inf, nan...```
- [cmath](https://docs.python.org/3/library/cmath.html)
```phase(complex(-1.0, 0.0)), and then most of the above with complex numbers.```
- [random](https://docs.python.org/3/library/random.html#examples)
```random, choice(['win', 'lose', 'draw']), mean, ...```
- [built in functions](https://docs.python.org/3/library/functions.html)
```max, help, sum, ...```
# Installation
```bash
pip install cli-calc
```
- [pypi cli-calc](https://pypi.org/project/cli-calc/)
## Configuration
For convenience, add a shell script in ```~/bin```:
```bash
cd ~/bin
vi cli-calc
```
with the following lines:
*Note*: Please adjust the path!
```bash
path=~/path/to/your/cli-calc/
cd $path
python3 -m cli_calc
```
Make it executable:
```bash
chmod a+x cli-calc
```
then use it anywhere. :-)
```bash
echo "7+8" | cli-calc
cat foo.bar | cli-calc
cli-calc
```
## Help
```bash

--------------------------------------------------
cli-calc 0.3.1: Powerful yet easy command line calculator.
INPUT:
"q" for quit, "h" for help
"_" for last float value
"_int_" for last int value
"sin(pi/2)" for sinus, ...
"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
Also try "cos(pi/2)", "0xFF ^ 0b10", "2**8-1", "factorial(42)", "help(math)"
See https://docs.python.org/3/library/math.html, use without "math."
