     $no = floor($no / $divider);
     $i += ($divider == 10) ? 1 : 2;
     if ($number) {
        $plural = (($counter = count($str)) && $number > 9) ? 's' : null;
        $hundred = ($counter == 1 && $str[0]) ? ' and ' : null;

  }
  $str = array_reverse($str);
  $result = implode('', $str);
  $points = ($point) ?

Problem is in fourth line $point = round($number - $no, 2) * 100;. It throws error when subtraction give minus output.

try something like this

$point = round($no - $number, 2) * 100 ;
if($point < 0 ){
    $point = $point * (-1);
}

And problem solved.
