4-3 Complex Number Calculation Precautions
©The input/output range of complex numbers is normally nine digits for the mantissa and
two digits for the exponent. If there is no exponent display, however, the mantissa can
be up to 10 digits.
When a complex number has more than 16 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.
*20 bytes of memory are used whenever you assign a complex number to a value memory
(page 40).
*The peed functions can be used with complex numbers.
