Now, with the CVS version the script says '34,9' instead of 34.9 (with
4.3.9 it was only '34').
This solves my problem, which was that calculations with variables,
type-converted from string to float had gone wrong sometimes. 
But it's still very strange.
I figured out that the problem only occurrs if the apache webserver
with php on it already ran for a few hours.

Please try using this CVS snapshot:

For Windows:

Description:
------------
A very strange problem occurs on my webserver. If you run the provided
code via http://knmm.de/bug.php a few times, in about 1 out of
10 times
the second line of output is "$price is a double with value 34". This
shows up randomly.
Running the script on the commandline of the same machine doesn't show
this behaviour.

Reproduce code:
---------------
$price = '34.90';

echo "\$price is a ".gettype($price)." with value $price\n";
settype($price,'double');
echo "\$price is a ".gettype($price)." with value $price\n";

(also available via http://knmm.de/bug.phps)

Expected result:
----------------
$price is a string with value 34.90
$price is a double with value 34.9


Actual result:
--------------
$price is a string with value 34.90
$price is a double with value 34
