In what scenarios would using the bc math functions in PHP be beneficial for accurate calculations involving decimal values?

When working with decimal values in PHP, floating-point arithmetic can sometimes lead to inaccuracies due to the way computers represent numbers. To ensure precise calculations with decimal values, the bc math functions in PHP can be used. These functions provide arbitrary precision arithmetic, allowing for accurate calculations with decimal numbers without loss of precision. 

// Using bc math functions for accurate decimal calculations
$number1 = '10.25';
$number2 = '5.75';

$sum = bcadd($number1, $number2, 2); // Add two numbers with 2 decimal places precision
$diff = bcsub($number1, $number2, 2); // Subtract two numbers with 2 decimal places precision
$mul = bcmul($number1, $number2, 2); // Multiply two numbers with 2 decimal places precision
$div = bcdiv($number1, $number2, 2); // Divide two numbers with 2 decimal places precision

echo "Sum: $sum\n";
echo "Difference: $diff\n";
echo "Product: $mul\n";
echo "Quotient: $div\n";
