Calculation Ranges, Number of Digits,
and Precision
The calculation range, number of digits used for internal calculation, and
calculation precision depend on the type of calculation you are performing.

Number of Digits for Internal
Calculation
15 digits
Precision
In general,
±
1 at the 10th digit for a single
calculation. Precision for exponential
display is
±
1 at the least significant digit.
Errors are cumulative in the case of
consecutive calculations.
