Default decimal

Can somebody please tell me what is happening here. I am posting a price from a form then putting it into a session.

$_SESSION['item_total'] = $_POST['item_total'];

echo $_POST['item_total'] . "--posted total<br>";
echo $_SESSION['item_total'] . "--session total<br>";

when i write it out this is the result what is happening to the .97
9.97--posted total
9--session total

Thanks in advance
mike

The problem is likely you allow php to define your variable types. If the first value that goes into your total is a 1, then the next is a 2.34. The variable may already be dimensioned in a way that doesn't allow the 2.34. Try to explicity define the data types of your variables to allow 9.97 or whaterver is your max value and see if you get different results. It is a lazy (bad) coding practice to allow php to define your variable types for you.
