How can the PHP server's configuration settings, such as precision and serialize_precision, impact the output of mathematical operations?

The PHP server's configuration settings, such as precision and serialize_precision, can impact the output of mathematical operations by controlling the number of decimal places displayed or the precision of floating-point numbers. To ensure consistent and accurate mathematical calculations, it is important to set these configuration settings appropriately based on the requirements of your application.

// Set the precision and serialize_precision configuration settings
ini_set('precision', 14);
ini_set('serialize_precision', -1);

// Perform mathematical operations
$num1 = 0.1;
$num2 = 0.2;
$result = $num1 + $num2;

// Output the result
echo $result;
