Big Number Calculator
Big Number Calculator
This tool performs arithmetic operations on arbitrarily large integers.
What Are “Big Numbers”?
In most programming languages, including standard JavaScript, numbers have a limit. The largest safe integer is `9,007,199,254,740,991`. Any calculation that goes above this number may lose precision and produce incorrect results.
This “Big Number Calculator” solves that problem by using `BigInt`, a special type in modern JavaScript. `BigInt` allows for calculations on integers of virtually unlimited size, perfect for cryptography, scientific calculations, or just very large numbers.
**Note:** This calculator only works with **integers** (whole numbers). It does not support decimals.

How to Use This Calculator
This tool is designed for performing basic arithmetic on very large integers.
- 1. Enter Numbers: Type or paste your first large integer into the “Number 1” box. Type or paste your second large integer into the “Number 2” box.
- 2. Decimals Not Allowed: You must use whole numbers only (e.g., `123456…`). Inputs like `1.5` or `1,234` will cause an error.
- 3. Choose Operation: Click one of the five operation buttons:
- `+` (Addition)
- `-` (Subtraction)
- `×` (Multiplication)
- `÷` (Division)
- `^` (Power / Exponentiation)
- 4. View Result: The result of the operation will appear in the green “Result” box at the bottom. You can copy the result from this box.
Important Notes on Operations:
- Division (÷): This calculator performs **integer division**. This means it discards any remainder. For example, `7 / 2 = 3` (not 3.5).
- Power (^): The second number (exponent) must be a positive integer. Negative exponents are not supported.
- Error Handling: If you divide by zero, use a non-integer, or enter invalid text, an error message will appear in a red box.
