• Even if the number of decimal places is specifi ed, internal calcu-
lation for a mantissa is performed up to 15 digits for The calcula-
tor, and the display value is stored in 10 digits. To round off those
values to the specifi ed number of decimal places, press [ 2nd ] [
RND ]. See Example 13.

Continuous calculation function

• The calculator enables you to repeat the last operation executed
by pressing [ = ] key for further calculation. See Example 14.
• Even if calculations are concluded with the [ = ] key, the result ob-
tained can be used for further calculation. See Example 15.

Answer function

• Answer function stores the most recently calculated result. It is
retained even after the power is turned off. Once a numeric value
or numeric expression is entered and [ = ] is pressed, the result is
stored by this function. See Example 16.
(Note) : Even if execution of a calculation results in an error, how-
ever, Answer memory retains its current value.
Scientifi c Calculation
Use the COMP mode for scientifi c calculations.

Logarithms and Antilogarithms

• The calculator can calculate common and natural logarithms and
anti-logarithms using [ log ], [ ln ], [ 2nd ] [ 10
See Example 17~19.

Fraction calculation

Fraction value display is as follow :

(Note) :Values are automatically displayed in decimal forma
whenever the total number of digits of a fractional values
(integer + numerator + denominator + separator marks)
exceeds 10.
