Bug description: decimal values stored in session variables not reliable
Description:
------------
trying to save a decimal number in a session value
Run badsave.php to store a value.
Seems to recall it ok within that scripts.
Running badrecall.php retrieves some other number.
the test number here 127.27 returns 72.035156309605
most other numbers ok, in quotes its ok.
Reproduce code:
---------------
<?
/*badsave.php*/
session_start();
$n=127.27;
store($n);
recall();
function store($n=0){
echo "saving $n";
$_SESSION["badno"]=$n;
}
function recall(){
session_start();
$n=$_SESSION["badno"];
echo "<br>recall $n";
}
?>
<?
/*badrecall.php*/
session_start();
$n=$_SESSION["badno"];
echo "<br>recall $n";
?>
Expected result:
----------------
just echo 127.27 to the screen
Actual result:
--------------
echo returned 72.035156309605
instead.
