From:             
Operating system: Linux / Unix
PHP version:      Irrelevant
Package:          Unknown/Other Function
Bug Type:         Bug
Bug description:Serialize problem with float data

Description:
------------
The problem appears when I want to serialize data like this the test script
submitted 


Output of var_dump : 

string(201)
"a:2:{s:5:"exVAT";a:2:{i:0;d:12.1199999999999992184029906638897955417633056640625;i:1;d:12;}s:6:"incVAT";a:2:{i:0;d:4566768.679999999701976776123046875;i:1;d:34343.33999999999650754034519195556640625;}}"


As you can see, the float data became very long... 
I saw that isn't a bug, but coming from floating data type :

=> http://www.math.byu.edu/~schow/work/IEEEFloatingPoint.htm


Test script:
---------------
// Test float 

function NumericPoint($Data)
{
  return round(floatval(str_replace(',','.', $Data)), 2);
}

$tab = array("12.1222", "12", "4566768.67676767", "34343.34343434343434");

$infos = array("exVAT" => array(0 => NumericPoint($tab[0]),
      1 => NumericPoint($tab[1])),
    "incVAT" => array(0 => NumericPoint($tab[2]),
      1 => NumericPoint($tab[3])));

$SeriaData = serialize($infos);


var_dump($SeriaData);

// End

Expected result:
----------------
I expect to see the good format of my float data

Actually, to patch this, I don't convert my string to a float and I use
str_replace on my serialize data to delete the double quote and change 's'
by 'd'
