### Algorithm and Formula

The core algorithm used in the Hex to Decimal Converter Tool is as follows:

- Start by initializing a variable
`decimal`

to zero. - Starting from the right-most digit of the hexadecimal number, work your way left.
- For each digit, multiply the digit by 16 raised to the power of the digit's position.
- Add the result to the
`decimal`

variable. - Repeat steps 3 and 4 until you have processed all the digits in the hexadecimal number.
- The final value of the
`decimal`

variable is the decimal equivalent of the hexadecimal number.

The formula for converting a hexadecimal number to decimal is:

`decimal = digit_n _ 16^n + digit_n-1 _ 16^n-1 + ... + digit_0 \* 16^0`

### Example Codes

printf("%d\n", decimal_num);
return 0;
}
```

#### JavaScript

```
let hex_num = "499602d2";
let decimal_num = parseInt(hex_num, 16);
console.log(decimal_num);
```

#### Java

public class HexToDecimal {
public static void main(String[] args) {
String hex_num = "499602d2";
int decimal_num = Integer.parseInt(hex_num, 16);
System.out.println(decimal_num);
}
}
```

#### PHP
