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.
Calculation Range and Precision
Calculation Range ±1 × 10
–99
to ±9.999999999 ×

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.
