How can trailing numbers behind decimal places be prevented when using PHP's floatval function?

edit

One way to prevent trailing numbers behind decimal places when using PHP's floatval function is by using number_format function. For example:

$number = floatval('10.12345678');
echo number_format($number, 2); // Output: 10.12

In this example, number_format is used to format the float value to two decimal places, which will prevent any trailing numbers after the second decimal place.
