Large-Number-Calculator

A large number calculator that can perform calculations on numbers with digits up to several thousand.

Key Features:

1. HTML Structure:

   • The webpage is structured with a div element for the calculator that contains an input for the display and buttons for input and operations.

2. CSS Styling:

   • The design has a modern feel with rounded corners, shadows, and smooth transitions.
   • The background is a gradient, and the layout is centered both vertically and horizontally using Flexbox.
   • Buttons have hover and active effects, making them interactive and visually appealing.

3. Google Fonts:

   • The Roboto font is loaded from Google Fonts for a clean and modern text appearance.

4. JavaScript Functionality:

   • appendToDisplay(value): Adds the clicked button value to the display.
   • clearDisplay(): Clears the input field.
   • calculateResult(): Evaluates the expression entered in the display, converting percentages and exponentiation symbols (^), and using BigInt for large number calculations.

5. Big Number Support:

   • The calculator can handle large numbers by converting numeric expressions into BigInt format, which allows for operations on integers larger than the normal JavaScript number type.

6. Interactive Buttons:

   • Special functions include clear (C), exponentiation (^), percentage (%), and calculation (=). The design distinguishes the special buttons visually with different colors.
