# 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 of a complex number equals
zero, that part is not displayed in rectangular
form.
