PHP String to Float
$rootbeer = (float) $InvoicedUnits;Should do it for you. Check out Type-Juggling. You should also read String conversion to Numbers.
You want the non-locale-aware floatval function:
float floatval ( mixed $var ) - Gets the float value of a string.
Example:
$string = '122.34343The';$float = floatval($string);echo $float; // 122.34343
Well, if user write 1,00,000 then floatvar will show error. So -
floatval(preg_replace("/[^-0-9\.]/","",$input));This is much more reliable.
Usage :
$input = '1,03,24,23,434,500.6798633 this';echo floatval(preg_replace("/[^-0-9\.]/","",$input));
