Is there a recommended approach for handling floating-point numbers in PHP to avoid precision issues?

Floating-point numbers in PHP can sometimes lead to precision issues due to the way they are stored in memory. To avoid these problems, it's recommended to use the `bcmath` extension, which provides arbitrary precision arithmetic. By using functions like `bcadd()`, `bcsub()`, `bcmul()`, and `bcdiv()`, you can perform calculations with higher precision. 

// Example of using the bcmath extension to handle floating-point numbers with higher precision
$num1 = '0.1';
$num2 = '0.2';

$sum = bcadd($num1, $num2, 10); // Adding two numbers with 10 decimal precision
echo $sum; // Output: 0.3
