Description:
------------
I don't get the expected result from sprintf(), when input are less than [-]1.

Tried the same code on a php 5.0.0b3 (windows), where I got the expected result.

Maybe its related/oposite to bug #28633


Reproduce code:
---------------
$fmt = "%08.2f";
printf("[".$fmt."]<br />",   -10);
printf("[".$fmt."]<br />",    -1);
printf("[".$fmt."]<br />",    -0.995);
printf("[".$fmt."]<br />",    -0.99);
printf("[".$fmt."]<br />",    -0.5);
printf("[".$fmt."]<br />",     0);
printf("[".$fmt."]<br />",     0.5);
printf("[".$fmt."]<br />",     0.99);
printf("[".$fmt."]<br />",     0.995);
printf("[".$fmt."]<br />",     1);
printf("[".$fmt."]<br />",    10);


Expected result:
----------------
[-0010.00]
[-0001.00]
[-0001.00] // Not [-0000.99], should't it round down ?
[-0000.99]
[-0000.50]
[00000.00]
[00000.50]
[00000.99]
[00001.00] // Not [00000.99] , should't it round up ?
[00001.00]
[00010.00]

Actual result:
--------------
[-0010.00]
[-0001.00]
[-0000000.99]
[-0000000.99]
[-0000000.50]
[00000000.00]
[00000000.50]
[00000000.99]
[00000000.99]
[00001.00]
[00010.00]

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Both PHP 4 and 5 return the same expected output. 
[-0010.00] 
[-0001.00] 
[-0000000.99] 
[-0000000.99] 
[-0000000.50] 
[00000000.00] 
[00000000.50] 
[00000000.99] 
[00000000.99]
