The actual result of the above calculation is 24.66666666… (and so on to infinity),
which the calculator rounds off. The calculator’s internal capacity is 15 digits for the
values it uses for calculations, which avoids accuracy problems with consecutive
operations that use the result of the previous operation.
6. Other Useful Calculation Features
