Data Input Precautions

• inputs the same data twice.
• You can also input multiple entries of the same data
A G
using
for example, press 20
• The above results can be obtained in any order, and not
necessarily that shown above.
• Precautions when editing data input for standard devia-
tion also apply for regression calculations.
• Do not use variables A through F, X, or Y to store data
when performing statistical calculations. These variables
are used for statistical calculation temporary memory,
so any data you may have assigned to them may be
replaced by other values during statistical calculations.
• Entering the REG Mode and selecting a regression type
(Lin, Log, Exp, Pwr, Inv, Quad) clears variables A through
F, X, and Y. Changing from one regression type to an-
other inside the REG Mode also clears these variables.

CMPLX ...........................................................
• 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. 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
