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.

A B 1(Mcl) <

• Example: 193.2  23 

8.4

193.2 A j 1 \ 23 <

193.2  28 

6.9

p 1 \ 28 <

Complex Number Calculations

Use the F key to enter the CMPLX Mode when you want to perform

calculations that include complex numbers.

CMPLX .......................................................................................... F 2

•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.

• Example: (23i )(45i)





(Real part 6) 2 + 3 i + 4 + 5 i <

(Imaginary part 8i ) A r
