(While using your calculator, not all the symbols shown will be displayed at once.)
If the value of the mantissa (fractional part) is not between ±0.000000001 and ±9999999999,
the number will be display in scientific notation. The display mode can be modified to meet a
particular requirement.
/ : This symbol will show on the display when the equation being entered or the result ob-
tained cannot fit completely in the display. Press the keys in order to view the missing
(hidden) part of the equation/result.
2ndF: This symbol will show on the display when you press the 2ndF key, and indicates that the
secondary functions shown in yellow on the keys are available.
HYP: After pressing the hyp key, this abbreviation will appear on the display to indicate that the
hyperbolic functions are available. If you enter the combination "2ndF arc hyp", the symbols
"2ndF HYP" will appear on the display to indicate that the inverse hyperbolic functions are
available.
ALPHA: This indicates that the keys 2ndF ALPHA or STO RCL have been pressed and that you
can consult or modify a variable stored in the memory, or use the statistical functions.
FIX/SCI/ENG: This indicates the notation used to display the value, and it changes each time
after the 2ndF and FSE keys are pressed.

Method used for representing the keys in these instruction manual
A special notation to describe the keys of the calculator is used throughout this manual. The keys
on the front of the calculator make it possible to access functions (numbers, calculations, func-
tions etc.) that are indicated by the characters shown on the keys, above them and on their side.
In order to use a logarithmic function, press the ln key.
In order to use an exponential function, press 2ndF first, and then the ln key.
To use the temporary memory X, press 2ndF first, then ALPHA and finally the ln key.
