This tool converts a given binary number into its 2’s complement representation.

### How to Use the 2’s Complement Calculator

To use the 2’s Complement Calculator, follow these steps:

- Enter the integer number you want to convert to its 2’s complement form in the “Enter a number” field.
- Specify the number of bits in the “Number of bits” field. The minimum value for bits is 1.
- Click the “Calculate” button to get the 2’s complement result.

### How It Calculates the Result

The calculator converts a given integer to its 2’s complement representation based on the number of bits specified. It follows these steps:

- Checks if the number fits within the provided bit width.
- If the number is negative, it calculates the 2’s complement by inverting the bits of the absolute value and adding one.
- Displays the result in binary form, showing padding zeros based on the number of bits.

### Limitations

The current version of the calculator has some limitations:

- If the specified number of bits is insufficient to represent the number, the result may be incorrect or displayed incorrectly.
- The input number should be an integer.
- Handling of non-integer inputs, non-numeric inputs, and very large bit values may be limited.

## Use Cases for This Calculator

### Calculating Positive Decimal Numbers

Start by entering the positive decimal number you want to convert into 2’s complement. The calculator will automatically show you the binary representation of the number in 2’s complement form. You can easily copy the binary output for your use.
