PyQt6 Calculator

This project is a basic calculator GUI application built using Python and the PyQt6 library. It features a user-friendly interface with a variety of functionalities including arithmetic operations, memory storage, and special operations like percentage and square root calculation.

Features

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• Memory functions: store and recall values.
• Percentage calculation and square root functions.
• Error handling for invalid operations (e.g., division by zero).
• Visual display of inputs and results using an LCD display.

Setup

1. Clone the repository:

   git clone https://github.com/JefeThePug/calculator.git
   cd calculator

2. Install required libraries (if not already installed):

   pip install PyQt6

Usage

Run the game from the command line by executing:

    python calculator.py

Code Overview

Main Components

• Colors: Custom colors for various parts of the application are defined at the start for easy theme adjustments.
• Calculator Window: The main window (inherited from QMainWindow) contains the layout and functionality for buttons, the display, and memory indicators.
• Button Actions: Buttons are dynamically created and linked to their respective operations using partial functions.
• Operations: Functions handle different operations:
  • append_to_number: Manages number entry, including decimal handling.
  • add_operator: Adds arithmetic operators.
  • totaling: Evaluates the expression when = is pressed.
  • percent, square root (√), and memory functions (MR, M+, MC): Provides additional operations.
  • clear, clear_mem: Reset and memory clearing functions.

Error Handling

• Displays ERROR on the LCD display for cases such as division by zero or invalid input.

File Structure

All functionalities are contained within a single file, making it easy to run as a standalone application.

Future Improvements

Potential future updates could include:

• Adding more complex operations (e.g., trigonometric functions).
• Saving calculation history.
