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.

23 digits
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.
