One of the ways to define decimal value precision is rounding. You can use round($number, $precision)

With your example it would look like so:

round($calvat+$itemtotal+$servicetotal-($discount+$pdiscount), 2);

round is not well suited to output a float value rounded to a certain number of decimal places. sprintf or number_format is better. – jspit Nov 18 '22 at 13:31
