As I understand it, you just want to truncate the number, without
rounding.
I think you are right, there isn't a function to do it for you but the
following code should do it:
intval(4.623 * 10)/10
or more generally:
function truncate_number($mynumber,$places) {
return intval($mynumber * pow(10,$places))/pow(10,$places);
}
