CMPLX ...........................................................
• The current angle unit setting (Deg, Rad, Gra) affects
CMPLX Mode calculations. You can store an expres-
sion in CALC memory while in the CMPLX Mode.
• Note that you can use variables A, B, C, and M only in
the CMPLX Mode. Variables D, E, F, X, and Y are used
by the calculator, which frequently changes their values.
You should not use these variables in your expressions.
• The indicator "R↔I" in the upper right corner of a
calculation result display indicates a complex number
result. Press
real part and imaginary part of the result.
• You can use the replay function in the CMPLX Mode.
Since complex numbers are stored in replay memory in
the CMPLX Mode, however, more memory than normal
is used up.
