Casio fx-50F A Function Calculation Input Ranges and Precision, k Calculation Ranges, Number of Digits, and Precision

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 five 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	±1×10–99to ±9.999999999×1099 or 0
Internal Calculation	15 digits
	In general, ±1 at the 10th digit for a single calculation. Error in the
Precision	case of a calculation result in exponential format is ±1 at the least
	significant digits of the mantissa. Errors are cumulative in the case of
	consecutive calculations.
