Question about Casio FX-115ES Scientific Calculator

1 Answer

I have the casio fx 115 and I am not sure exactly what modes to keep it in, such as cmplx or comp, and/or deg or rad. I am trying to find e^(0.03*5) but the calculator says syntax error. What is going on? Thank you.

I get an answer of one.
To clear your calculator back to default, to the following:

shift
CLR (the button 9)
3 (select option 3 = All
= (the equal button)
AC (the red AC button)

Your calculator is now reset to factory settings
Now try your calculation.

Fix the mode


Try a reset SHIFT 9 (CLR) and reset 3:All
Also if Mode:1: COMP gives Complex, maybe MODE:2:CMPLX will give you the usual COMP mode. (wires may be crossed). I have a calculator that has two keys inverted. I made a note of it and keep it taped inside the sliding cover.

How can I reset my Casio FX-115 ES calculator to its default settings


There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.
To do statistics you must put the calculator in STATS mode.
Press MODE: You have 6 computational modes to choose from
1: COMP, the general computational mode
2:CMPLX, for calculation s with complex numbers,
3: STAT for statistics,
4: Base-N, binary, octal, decimal, and hexadecimal numeration
5: Equation, solving mode, etc..
For statistics, choose 3:STAT

My fx_115ES casio is displaying Dec and I don't know why!


You're in BASE-N mode for integer arithmetic. Press MODE 1 to get to COMP mode for real arithmetic or MODE 2 for CMPLX mode for complex arithmetic.

How to get the imaginary numbers on the 115es casio calculator? It is in purple and i cant get it with shift.


You need to be in complex mode before you can do any calculations involving complex numbers. Press MODE 2 to switch to CMPLX mode. When you're done, press MODE 1 to switch back to COMP mode. (Yes, the names are confusing. I didn't pick them.)

Casio fx 992s when i try to do simple calculations like 1.33360 - 1.33041.....the answer is 3.19 and other little numbers in the top right. i dont get this or like this. i want a proper 5 decimal...


It sounds like you need a manual for your calculator. You can download a scanned copy here, and it will explain what all the keys are for. For now, here is the way to set the calculator for a five decimal place display:
  1. Press the MODE key three times. A menu offering choices of FIX, SCI or NORM will appear.
  2. Press the 1 key to select FIX mode. The message "0~9?" will appear.
  3. Press the 5 key. This tells the calculator to display five digits after the decimal.
This mode setting will hold until you change it to something else, or when you turn off the calculator.

Spend some time reading the manual and work with the calculator. It's a powerful tool with a lot of capabilities. Thanks for using Fixya!

Problem with Casio FX 260 Calculator


Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

PROBLEM W/ CASIO fx-260 SOLAR


Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions
  1. calculator must not be in SD mode, hence it is in COMP mode
  2. An angle unit must be shown on display.
Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.
