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'
