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.
Calculation Range and Precision
Calculation Range ±1 × 10
-99
to ±9.999999999 × 10
99
or 0
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.
