Rounding errors in sums do not occur because we use a certain number of digits after the decimal point. The source of the such errors is the '''floating point''' representation of decimal fractions. As you can see, when using '''fixed point''' representation, there are no rounding errors. Of course, the calculated sum of a / 3 + a / 3 + a / 3 is less than a, but this error is caused by the rounding at division.
