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 “RI” in the upper right corner of a
calculation result display indicates a complex number
result. Press
A r to toggle the display between the
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.
