The problem is that many values can't be accurately stored as binary values -- there is always some rounding involved. The value 0.1 in binary is:

1100110011001100110011001100110011... ad infinitum.

So somewhere along the line, some rounding is done. The net result is that the value depends on the precision it's stored in.

But apart from looking a bit odd, what practical problem is there with the result you have above?
