4-2 Performing Complex Number Calculations The following examples show how to perform each of the complex number calculations available with this calculator. k Arithmetic Operations [OPTN]-[CPLX]-[i] Arithmetic operations are the same as those you use for manual calculations. You can even use parentheses and memory.

Performing Complex Number Calculations 4-2 k Complex Number Calculation Precautions • The input/output range of complex numbers is normally 10 digits for the mantissa and two digits for the exponent. • When a complex number has more than 21 digits, the real number part and imaginary number part are displayed on separate lines. • When either the real number part or imaginary number part equals zero, that part is not displayed.
