The precise details of rounding are very machine-dependent and you are
not entitled to make assumptions about them. Don't forget that there is
rounding in the additions as well as in the representation of "0.2". It
is a grave mistake to use floating-point arithmetic to control a loop which
has to iterate an exact number of times.
