Rounding Number e.g. 8.5 to 9

[xplosiongames]

$query2 = "SELECT * FROM table WHERE genre = 'action'";
              $results = mysql_query($query);

          $amount = "0";

          while ($amountline = mysql_fetch_assoc($results2)) {
          $amount++;
          }
          $dividedby4 = $amount / 4;

To start with '$amount' is equal to 34.
Therefore '$dividedby4' is equal to 8.5.

I wish to be able to round the 8.5 up or down.

Also whether or not you can actually figure out how much is after decimal e.g. 0.87

(if this made sense)

Anyone got any clues?

Sorry just looked through my PHP book and sorted it..

Simple really!! lol

$query = "SELECT * FROM table WHERE genre = 'action'";
              $results = mysql_query($query);
              $query = "SELECT * FROM tbl_gameinfo WHERE gameinfo_genre = 'action'";
              $results2 = mysql_query($query);
              $amount = "0";
              while ($amountline = mysql_fetch_assoc($results)) {
              $amount++;
              }
              $divby4 = $amount / 4;
               $i =  $divby4  - floor($divby4);
            echo ($i);

floor will always round down. To round it according to mathematic rules you should use [man]round[/man].
