Description:
------------
With those exemples, i have a return value false.
Here are my tests value :
42, -42, +42, .4, -.4, 1000000000000, -1000000000000

Why i ask this report because i find important to check 
float value with integer value.
Exemple : Calc program :
input text form : type 0.45
input text form : type 0.55
Choose add action = 1 //Perhaps ajax or javascript so i 
return 1 to program in form.
Or i choose to type '1' in input form.


Reproduce code:
---------------
<?php
//$_GET['myfloat0'] == '42';
//$_GET['myfloat1'] == '-.4';
$source = INPUT_GET;
$name = 'myfloat0';
$ret = input_get($source, $name, FILTER_VALIDATE_FLOAT);
var_dump($ret);

$source = INPUT_GET;
$name = 'myfloat1';
$ret = input_get($source, $name, FILTER_VALIDATE_FLOAT);
var_dump($ret);

?>


Expected result:
----------------
float(42)
float(-0.4)


Actual result:
--------------
bool(false)
bool(false)

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.
