This arises because finite floating point arithmetic is not exact so 2.8/0.1 results in 27.999999999999996. And, since the int() function truncates towards zero, this results in a value of 27. If you want the nearest integer you should use round(x) rather than int(x). -- https://mail.python.org/mailman/listinfo/python-list
