Calculation Range and Precision
Calculation Range: ±1 × 10
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.

• Error is cumulative and tends to be large in the vicinity of a function's
singular point and inflection point.
• Accumulation of errors tends to occur during statistical calculations
involving data in which there is a large number of decimal places
and there is little difference between data items. Input of statistical
data is limited to six decimal places.
