Calculation Range	±1 × 10-99 to ±9.999999999 × 1099 or 0
Number of Digits for Internal Calculation	23 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.

Precision is basically the same as that described under "Calculation Range and Precision", above.

xy, x√y, x!, nPr, nCr type functions require consecutive internal calculation, which can cause accumulation of errors that occur with each calculation.

Error is cumulative and tends to be large in the vicinity of a function’s singular point and inflection point.

The range for calculation results that can be displayed in π form when MathI/MathO is selected for Input/Output on the SETTINGS menu is |x| < 106. Note, however, that internal calculation error can make it impossible to display some calculation results in π form. It also can cause calculation results that should be in decimal form to appear in π form.
