This can be done by setting the calculator to the right MODE. Press MODE 9 to turn on scientific notation. For example, compute 1 / 200 = and you will see 5 with a -03 exponent in the upper right. Press MODE 9 again and it will be displayed .005

To enter numbers in scientific notation use the EXP at the bottom. To enter .005, press 5 then EXP then +/- then 3. You will see it displayed. Then you can perform calculations with this entered number.

How do I change from having the answers displayed in scientific notation to normal number display?


You can set your display mode to FIX or NORMAL ( 1 or 2) if you have them. However if the result is too small ( less then 0.001) or too large the calculator will use the scientific format. Generally if there are not enough display positions to show your result, the calculator uses scientific notation.

How do i take off scientic mode just a regualer:


Press SHIFT [SETUP]. You can select FIX for fixed-decimal or NORM for normal display. For FIX the calculator will prompt for the number of digits. NORM gives you two choices: 1 will display numbers of magnitude less than 10E-2 in scientific notation, 2 won't switch to scientific notation until the magnitude drops below 10E-9.

Trying to get calculator to display in scientific notation


Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.
You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.

If you do not want fractions nor radicals set the default Input/Output format to LineIO.
To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.

How do I input a mumber in scientific notation?


The structure of a number in scientific notation is as follows
one digit [decimal mark] several digits power of 10 (- sign if needed) up to two digits for the exponent.
d.ddddd [10^] (-) dd

To enter a number in scientific notation you need to use the [EXP] key, between the [.] and the [=] sign, on the bottom row of keys.

Ex: Avogadro's number (do not worry if you do not know what it represents)
Na= 6.02 x10 ^23
6.02 [EXP] 23 [=]

Electron charge 1.6 x10 ^(-19)
1.6 [EXP] [+/-] 19 [=]
The [+/-] key is the change sign key, in the first column of keys, between the fraction key [a b/c] and the [7] key

Hi, I have a Casio calculator fx-991MS giving me wrong answers!


Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

Does the fx-260 SOLAR do exponential calculations?


Hello,
Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.
Hope it helps.

My casio fx-115ES is stuck in scientific notation


The FX-115ES can only handle ten digits. 14! is an eleven-digit number, thus the calculator can only display the first ten digits and a power of ten.
