kVariables
• 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:
0
A
j
1
. This operation deletes the data assigned to
variable A.
• Perform the following key operation when you want to clear the values
assigned to all of the variables.

Complex Number Calculations
Use the
F
key to enter the CMPLX Mode when you want to perform
calculations that include complex numbers.

• 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.
