        for($X=count($_AV);$X>=0;$X--)
   {
              if ($_AV[$X]== $arg)
             {
                $result=$X;
                break;
            }

           else if(($_AV[$X]<$arg) AND ($arg-$_AV[$X] <=$diff)
            {
             $result=$X;
                break;
           }

 else if(($_AV[$X]>$arg) AND ($_AV[$X]-$arg<=$diff)
            {
             $result=$X;
                break;
           }
