Complex Number Calculations
# 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 part and imaginary part are
displayed on separate lines.
# When either the real part or imaginary part
of a complex number equals zero, that part is
not displayed in rectangular form.
# The following functions can be used with
complex numbers.

k Extraction of Real and Imaginary Parts [OPTN] - [CPLX] - [ReP]/[lmP]
Use the following procedure to extract the real part a and the imaginary part b from a
complex number of the form
a + b i .
