Senolop: RPN Calculator

Welcome to Senolop, a powerful Reverse Polish Notation (RPN) calculator! This calculator allows you to perform mathematical operations using the classic postfix notation. With its intuitive stack-based approach, Senolop offers a unique way to solve complex equations.

Features

• Efficient and easy-to-use RPN calculator
• Supports basic arithmetic operations: addition, subtraction, multiplication, and division
• Performs calculations using a stack-based mechanism
• Error handling for incorrect inputs and division by zero
• Memory functionality with a built-in memory stack
• Customizable precision settings for accurate calculations

Installation

Senolop is a command-line application written in Python. To use it, make sure you have Python 3.x installed on your system. Follow these steps to install Senolop:

1. Clone the repository:

git clone https://github.com/ssouzawallace/senolop.git

2. Change into the project directory:

cd senolop

3. Run the application:

xcrun Senolop.xcproj

Usage

Senolop provides a simple and efficient way to perform calculations using RPN notation. Follow these guidelines to start using Senolop:

1. Enter numbers and operators in the desired order, separated by spaces.

   • Example: To calculate 4 + (7 - 2) * 5, enter 4 7 2 - 5 * +.

2. Press Enter to display the result.

3. Senolop will evaluate the expression and provide the output.

4. The calculator supports the following operators: +, -, *, and /.

5. To clear the stack, type clear or press Enter without entering any input.

6. To store a number in memory, use the sto command followed by the memory slot number and the number to be stored.

   • Example: sto 1 saves the top element from the stack to memory slot 1.

7. To recall a number from memory, use the rcl command followed by the memory slot number.

   • Example: rcl 1 retrieves the value stored in memory slot 1 and pushes it to the stack.

8. To change the precision settings, use the precision command followed by the desired number of decimal places.

   • Example: precision 4 configures Senolop to display results with four decimal places.

Examples

• Addition:

  • Input: 5 2 +
  • Output: 7

• Subtraction:

  • Input: 9 3 -
  • Output: 6

• Multiplication:

  • Input: 4 5 *
  • Output: 20

• Division:

  • Input: 10 2 /
  • Output: 5

• Mixed operations:

  • Input: 4 3 * 8 2 + /
  • Output: 0.5714

• Storing and recalling from memory:

  • Input: 7 3 + sto 1 rcl 1 -
  • Output: 7
