# Simple zsh calculator
> This is a calculator which runs on zsh.
### Demo
### Installation
1. Clone this repository to your favorite path (e.g. `~/.oh-my-zsh/plugins/calc/calc.plugin.zsh`)
2. `source` the file in your `.zshrc`
3. Restart your `zsh`
```sh
# Your .zshrc
source $HOME/.oh-my-zsh/plugins/calc/calc.plugin.zsh
```
#### Via [antigen](http://antigen.sharats.me/)
Add to `.zshrc`
```sh
antigen bundle arzzen/calc.plugin.zsh
```
#### Via [zplug](https://github.com/zplug/zplug)
Add to `.zshrc`
```sh
zplug "arzzen/calc.plugin.zsh"
```
### Usage
```bash
# addition
root@pc:~$ = 5+3
8
# multiplication
root@pc:~$ = '4*2'
8
# subtraction
root@pc:~$ = -4-2
-6
# division
root@pc:~$ = 5.0/2
2.5
# square root
root@pc:~$ = sqrt(2)
1.41421
# parentheses
root@pc:~$ = "(6+6)*6"
72
# convert from decimal to hexadecimal
root@pc:~$ = "[#16] 255"
16#FF
# convert from decimal to binary
root@pc:~$ = "[#2] 12"
2#1100
# convert from binary to decimal
root@pc:~$ = "2#1100"
12
# convert from hexadecimal to decimal
root@pc:~$ = "16#FF"
255
# arctangent
root@pc:~$ = atan(1)
.785398
# PI value
root@pc:~$ = PI
3.14159
# more complex
root@pc:~$ = "3.4+7/8-(5.94*(4*atan(1)))"
-15.2611
```
### Alternative Implementations
```
# Put these in your .zshrc (No need to install a plugin)
cc() python3 -c "from math import *; print($*);"
alias cc='noglob cc'
# You can use `cc` just like `=` from above. All functions from the math module of Python are available for use.
```
### Plugin location
```bash
.oh-my-zsh
└─── plugins/
└─── calc/
