Remember that binary numbers need not have an exact decimal format with a limited number of digits, and the other way around. This is the reason for the old effect (not "problem"): 0.1 + 0.1 + 0.1 == 0.3 % FALSE! Considering this it will be very hard to define uniquely, what "all decimal places" mean.
