## Summary

This package contains a class Calculator which allows to perform basic mathematical operations
while saving the obtained result in memory for further calculations.

It includes methods for the following operations:

* Addition / Subtraction
* Multiplication / Division
* Take (n) root of a number
* Reset memory

## Requirements

* Python 3.6 or newer

## Installation

To install the package:

```bash
pip install gkamin-calculator
```

## Usage

This section will detail all the methods that can be called for the created object Calculator.

However, in order to use the methods, first we need to import the package:

```bash
>>>> from gkamin_calculator.gkamin_calculator import Calculator
```

### Creating the calculator object

When the calculator object is created, the initial value it stores is equal to zero:

```bash
>>>> calc = Calculator() 
>>>> print(calc.result)
0
```

Initial value can be changed by using optional input parameter:

```bash
>>>> calc = Calculator(10.05)
>>>> print(calc.result)
10.05
```

### Addition method

**.add(addend)** - this method adds input value to last stored result.
Initially to 0:

```bash
>>>>calc = Calculator()
>>>>calc.add(2)
>>>>print(calc.result)
2
```

```bash
>>>>print(calc.result)
2
>>>>calc.add(3)
>>>>print(calc.result)
5
```

### Subtraction method

**.subtract(subtrahend)** - this method subtracts input value from last stored result:

```bash
>>>>print(calc.result)
5
>>>>calc.subtract(1)
>>>>print(calc.result)
4
```

### Multiplication method

**.multiply(multiplier)** - this method multiplies input value by last stored result:

```bash
>>>>print(calc.result)
4
>>>>calc.multiply(4)
>>>>print(calc.result)
16
```

### Division method

**.divide(divisor)** - this method divides last stored result by input value:

```bash
>>>>print(calc.result)
16
>>>>calc.divide(2)
>>>>print(calc.result)
8
```

### Root method

**.root(degree_of_root)** - this method extracts n-th root from last stored result, where n is degree of root.

```bash
>>>>print(calc.result)
8
>>>>calc.root(3)
>>>>print(calc.result)
2
```

**.root(degree_of_root, radicand)** - if this is the first operation performed (initially radicand is equal to 0),
optional input value to be used to set required radicand value:

```bash
>>>>calc = Calculator()
>>>>calc.root(4, 64)
>>>>print(calc.result)
4
```

## Reset method

**.reset(self)** - this method resets the last stored result to zero:

```bash
>>>>calc.reset()
>>>>print(calc.result)
0
```
