recalculation value (Displayed only when there may be a possibility of
rounding error.)
• To account for possible rounding error, ClassPad additionally obtains the
result using the probability that is next lowest for the least significant digit. For
example, if the probability is 0.61, ClassPad would recalculate using 0.60. The
recalculation result is only shown if it is different from the original one.
