non significant zero are not return with sybase_fetch_ 
functions 

ex : decimal(10,2)

14.3 is return instead of 14.30 in database
100 is return instead of 100.00 in database

db : ase 11.9.2
os : w2k

code 
$ls_query = "select * from mytable";
$res = sybase_query($ls_query,$cnx);
  while ($op_by_int = sybase_fetch_array($res)) 
  {
      while (list( $key, $value ) = each( $op_by_int )) 
       {
               echo "<br>$key => $value";
       }
  }
  

thanks
