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.
Calculation Range and Precision

Precision | In general, π1 at the 10th digit for a single | |
| calculation. Precision for exponential | |
| display is π1 at the least significant digit. | |
| Errors are cumulative in the case of | |
| consecutive calculations. |
