How can PHP be used to manipulate decimal values, such as adding or formatting them for display purposes?
When manipulating decimal values in PHP, you can use built-in functions such as number_format() to format them for display purposes. To add decimal values, you can simply use the addition operator (+). Remember to pay attention to the precision and rounding issues that may arise when working with decimal values in PHP.
// Adding decimal values
$decimal1 = 10.5;
$decimal2 = 5.25;
$sum = $decimal1 + $decimal2;
echo "Sum of decimal values: " . $sum;
// Formatting decimal values for display
$number = 1234.56789;
$formatted_number = number_format($number, 2); // Format to 2 decimal places
echo "Formatted number: " . $formatted_number;
