k Calculation Ranges, Number of Digits, and
Precision
The calculation range, number of digits used for internal calculation, and calculation
precision depends 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.
