(5) Rounding
Example 74

Ahe/dw
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 precision problems with consecutive
operations that use the result of the previous operation.
6. Other Useful Calculation Features
(1) Answer Memory (Ans)
Calculation results are automatically stored in the Answer Memory, which means
you can recall the results of the last calculation you performed at any time.
u uu u uTo recall Answer Memory contents
Press ! and then K (which is the shifted function of the - key).
This operation is represented as ! K throughout this manual.
Example To perform 3.56 + 8.41 and then divide 65.38 by the result
Ad.fg+i.ebw
gf.di/ !Kw
(2) Consecutive Calculations
If the result of the last calculation is the first term of the next calculation, you can use
the result as it is on the display without recalling Answer Memory contents.
u uu u uTo perform a consecutive calculation
Example To perform 0.57
× 0.27, and then add 4.9672 to the results
