This is because of floating point inaccuracy. The system cannot accurately represent some integers, however it does its best to approximate them. Notice this: >>> x = 2.0/3 >>> x 0.66666666666666663 >>> round(x,2) 0.67000000000000004 >>> s = str(round(x,2)) >>> s '0.67' -- http://mail.python.org/mailman/listinfo/python-list
