Are there best practices for rounding numbers in PHP calculations to avoid inaccuracies?

When performing calculations in PHP, floating-point numbers can sometimes result in inaccuracies due to the way computers represent decimal numbers. To avoid these inaccuracies, it is recommended to round the numbers to a specific precision using PHP's built-in round() function. This ensures that the results are more accurate and reliable.

// Example of rounding a number to 2 decimal places
$number = 10.555;
$roundedNumber = round($number, 2);

echo $roundedNumber; // Output: 10.56
