In what scenarios would utilizing BC Math functions be more appropriate than PHP's built-in functions for handling decimal calculations?

When dealing with decimal calculations that require high precision and accuracy, utilizing BC Math functions in PHP would be more appropriate than PHP's built-in functions. BC Math functions offer arbitrary precision arithmetic, allowing for accurate calculations with decimal numbers without losing precision due to floating-point errors. 

$number1 = '0.1';
$number2 = '0.2';

// Using BC Math functions for precise decimal calculations
$sum = bcadd($number1, $number2, 10); // Sum of $number1 and $number2 with 10 decimal places precision

echo $sum; // Output: 0.3
