• Even if the number of decimal places is speci 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 speci 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-

ever, Answer memory retains its current value.
