• There are seven variables (A through D, M, X and Y), which can be used

to store data, constants, results, and other values.

• Use the following operation to delete data assigned to a particular

variable:

• The current angle unit setting (Deg, Rad, Gra) affects CMPLX Mode

calculations.

• Note that you can use variables A, B, C, and M only in the CMPLX Mode.

You cannot use variables D, X, and Y.

• The indicator “R

↔

I” 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.
