Question about Casio FX-115ES Scientific Calculator

Unfortunately you can't. If the magnitude of the number is too small or too large, the calculator automatically switches to scientific notation. Consider a number that has 30 zeros before it instead of the 3 in this example. How is that going to fit on the screen?

You should feel happy that your calculator can perform some exact calculations. If you do not want the exact values you can press the SD key. You can also press SHIFT EXE rather than EXE alone.

Hope it helps.

The answer that you have received in actuality is correct. However, it
is in exact form when the answer that you were looking for was an
approximation (decimal form) answer. To achieve this all you have to
do is hit the alpha button (the yellow button with a diamond in the
center) and then enter which will give you your desired answer :-)

You have to set how the calculator handles numbers. To do this follow these steps:
1. Press the 'MODE' button. This brings up the calculator's main settings page.
2. Scroll down until you reach a field titled 'Exact/Approx...'. This is the setting for how the calculator handles numbers, whether it will show the exact answer (which is usually in fraction format) or whether it will show an approximate number (which will be in decimal format).
3. Press the right arrow which will bring up the options for that setting. You must now choose between three ways of handling numbers:
-'1:AUTO' will determine which type of answer the calculator will give based on what numbers you want it to calculate (e.g. if you want an answer in decimal format just add a decimal somewhere in your problem).
-'2:EXACT' will automatically display all answers in either whole number format or in fraction format.
-'3:APPROXIMATE' will automatically display all answers in decimal format.
4. After you have selected one of those options press enter one more time to get out of the 'MODE' dialogue and return to the 'HOME' screen. Now try a problem and see what happens.
Personally I like using 'AUTO' because then I don't have to keep returning to 'MODE' when I want either or.
Hope this helped, I had the same problem when I first started using the TI-89.
