Note
When inputting a value in the CMPLX Mode, each value takes up two stack levels: one for the real
part and one for the imaginary part. This means that the numeric stack has only fi ve levels in the
CMPLX Mode.
k Calculation Ranges, Number of Digits, and Precision
The following table shows the general calculation range (value input and output range), number of
digits used for internal calculations, and calculation precision.
Calculation Range
±1×10
–99
to ±9.999999999×10
99
or 0
Internal Calculation
15 digits
Precision
In general, ±1 at the 10th digit for a single calculation. Error in the
case of a calculation result in exponential format is ±1 at the least
signifi cant digits of the mantissa. Errors are cumulative in the case of
consecutive calculations.
