I change the mode to comp but it changing automatically to cmplx

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.

SOURCE: I have the casio fx 115 and I am not sure exactly

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.

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**

I wish you had thought it worthwhile to specify the model of your calculator. We cannot possibly know them all. Anyway, if it is a Casio or Casio Clone, the computational mode is set to VERIFY. Change it to the general computational mode COMP. For a Casio, press [MODE] key then [1:COMP].

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.

"FIX" mode is the number of decimal places, When you say Fix-0 it will truncate the decimals.

Either set model FIX-4 or FIX-5 or better still, just regular COMP mode.

Shift-clr-2 (mode) should set it back to defaults.

Conversion of polar form to rectangular:

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in polar form, e.g. r = 3, θ = 42°: 3 [SHFT] [(-)] 42 [=]
- Switch to rectangular view: [SHFT] [2] [4]

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in rectangular form, e.g. real part = 2, imag part = 3: 2 [+] 5 [ENG] [=]
- Switch to polar view: [SHFT] [2] [3]

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.)

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:

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!

- Press the MODE key three times. A menu offering choices of FIX, SCI or NORM will appear.
- Press the 1 key to select FIX mode. The message "0~9?" will appear.
- Press the 5 key. This tells the calculator to display five digits after the decimal.

Press MODE 1 to select COMP mode (or MODE 2 for CMPLX).

The [MODE] key can be used to select the modes described below.

Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes

Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetric calculations

(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

SD: Single-variable statistical calculations

(sample standard deviation, etc.)

LR or REG: Paired-variable statistical calculations

(linear regression statistical calculations, etc.)

BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations

MAT: Matrix calculations (determinants, etc.)

VCT: Vector calculations

EQU: nth degree equations, simultaneous equations

2) Display Settings

Use these settings to control how calculation results are displayed.

Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

3) Angle Unit Setting

(90°=?/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads

4) Engineering Mode

Use this mode when you want to input and perform calculations using engineering symbols.
