# sc
**S**mall RPN **c**alculator written in Golang
## Usage
The most basic usage is just invoking the program name:
```
$ sc
```
Then you can enter values and commands ([see commands](#commands)):
```
$ sc
12
12.000000
15
12.000000
15.000000
+
27.000000
```
On the left, it is your input. On the right, the stack.
You can enter more than one value, as long as they are separated by spaces:
```
$ sc
100 200 add
300.000000
```
Moreover, you can pipe values into `sc`:
```
$ echo "2 10 pow" | sc
1024
```
It will display the last element of the stack.
## Commands
Supported commands are the following:
* `+`, `a`, `add`: Add the last two elements of the stack
* `-`, `s`, `sub`: Substract the last two elements of the stack
* `*`, `m`, `mul`: Multiply the last two elements of the stack
* `/`, `d`, `div`: Divide the last two elements of the stack
* `sw`, `swap`: Swap the last two elements of the stack
* `p`, `pop`: Pop the last element from the stack
* `q`, `quit`: Quit the program
* `c`, `clear`: Clear the stack
* `^`, `pow`: Do a power of the last two elements of the stack
* `sum`: Sum all the stack
* `sqrt`: Get the square root of the last element of the stack
* `h`, `help`: Display help
