Description:
------------
When passing a negative float to filter_data() and filtering on FL_FLOAT, a positive float is returned. It should return a negative float like FL_INT does for integers.

(I have a patch for this that I will submit.)

Reproduce code:
---------------
<?php
$float = '-34.78';

var_dump(filter_data($float, FL_FLOAT));
?>

Expected result:
----------------
float(-34.78)

Actual result:
--------------
float(34.78)

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
