What are the best practices for handling mathematical operations in PHP to ensure accurate results?

When performing mathematical operations in PHP, it is important to be aware of potential precision issues that can arise due to the way floating-point numbers are represented in computers. To ensure accurate results, it is recommended to use the BCMath extension in PHP, which provides arbitrary precision arithmetic functions. 

// Example of using BCMath extension for accurate mathematical operations
$num1 = '123456789012345678901234567890';
$num2 = '987654321098765432109876543210';

$result = bcadd($num1, $num2); // Adding two numbers
echo $result; // Output: 111111111011111111201111111100
