Accuracy and Rounding Information
Calculations are accurate to the tenth digit. When a
calculation result exceeds 9999999999, the first 10 digits
are displayed with a decimal point 10 places to the left of
its true position, and
E
is displayed. Position the decimal
point correctly by mentally moving it 10 places to the right
and inserting zeros as required.
Calculations with more than 10 digits to the right of the
decimal point are rounded to 10 digits.
