Initial Comment:
Seems to me like an error in int():

Python 2.2.3 (#1, Jun  5 2003, 21:12:33)
ÄGCC 3.2.3Ü on aix4
Type "help", "copyright", "credits" or "license" for
more information.

>>> print int((4.3 % 1)*10)
2
>>> print 4.3 % 1
0.3
>>> print 4.3 % 1 * 10
3.0
>>> print int(4.3 % 1 * 10)
2

Is this a bug ???

Ah, the joys of floating point.
Closing the bug as invalid.

Try displaying the penultimate result to full precision.  On my 
box I get this:

>>> 4.3 % 1 * 10
2.9999999999999982
>>>


int() of that is 2.  What do you get?  And have you read the 
Python Tutorial appendix on floating-point issues?
