kCalculation 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 ⋅ 10–99to ±9.999999999 ⋅ 1099 or 0
Number of Digits for Internal			15 digits
Calculation
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.
