• Pressing [ ENG ] or [ 2nd ] [
] will cause the exponent display
for the number being displayed to change in multiples of 3. See
Example 11.
• Even if the number of decimal places is specified, internal calcula-
tion for a mantissa is performed up to 15 digits for SR-270ll / SR-
275, and the display value is stored in 10 digits. To round off those
values to the specified number of decimal places, press [ 2nd ]
[ RND ]. See Example 12.
Continuous calculation function
• The calculator enables you to repeat the last operation executed
by pressing [ = ] key for further calculation. See Example 13.
• Even if calculations are concluded with the [ = ] key, the result ob-
tained can be used for further calculation. See Example 14.
Answer function
• Answer function stores the most recently calculated result. It is re-
tained 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 15.
(Note) : Even if execution of a calculation results in an error,
however, Answer memory retains its current value.
Scientific Calculation
ſ Use the COMP mode for scientific calculations.
Logarithms and Antilogarithms
• The calculator can calculate common and natural logarithms and
anti-logarithms using [ log ], [ ln ], [ 2nd ] [ 10
X
], and [ 2nd ] [ e
X
].
See Example 16.

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