Rounding value correctly
intval() does not round values correctly!!!!
As for C++, it simply converts to int and ignores decimal places. If you want a source value of say 5.6 to be converted to an integer of 6 and not 5, then use:
$MyIntValue = intval(round(5.6)); //<<< intval() because round() outputs a floatRound down
$MyVariable = floor(56.78); //Returns 56Round Up
$MyVariable = ceil(56.78); //Returns 57Round to a specific number of decimal places
echo round(12.3456789, 3); //Will print: 12.346Value output vs string output
//Force to 2 decimal places (outputs as a string, so "6.30")
$MyString = number_format("6.3",2); //Will display 6.30
//Force to 2 decimal places (outputs as a number, so 6.30)
$MyValue = round("6.3456",2); //Will output 6.30
