How does PHP handle precision and rounding errors when performing mathematical operations?

PHP handles precision and rounding errors when performing mathematical operations by using functions like round(), ceil(), and floor() to round numbers to a specified precision. Additionally, PHP offers the bcmath extension for arbitrary precision mathematics, which allows for precise calculations with large numbers.

// Using round() function to handle precision and rounding errors
$number = 10.555;
$rounded_number = round($number, 2);
echo $rounded_number; // Output: 10.56
