Question about Casio FX-115ES Scientific Calculator

Re: CFX-9850GaPlus

"Decimal to fraction is a non trivial calculation that can have multiple answers so doesn't lend itself to a calculator feature."

LOL i hope u are being ironic...

anyway the check list for f-d to work:

-mode comp (wich u allready have)

-display norm1 or norm2

in the LINK from main menu make sure Image set mode is OFF

Re: CFX-9850GaPlus

I think the F-D function only works one direction from fraction to decimal. Decimal to fraction is a non trivial calculation that can have multiple answers so doesn't lend itself to a calculator feature.

Turn calculator On.

If you see no icons, press the Menu key.

Press 1 or use arrow keys to bring focus on RUN.

In Run scree press SHIFT MENU to enter SetUp

Use Arrow Down repeatedly till you reach the line Display.

Press the F1 key to select FIX

You can then specify the number of decimal digits to keep in your results, by pressing one of the function keys. You will be able to select 0 to 9 decimal digits.

None of these solutions answer his question. When converting a fraction or any number with decimal places to Binary, the TI-89 gives "Error: Domain error." For example, entering .6875 [2ND][MATH][BASE][BIN] does not work. I haven't found a way to do it with built in functions. In order to do these types of conversions, I use the following method.

Convert: 0.6875 to Binary

- left of decimal is a 0, so write down a 0, then a decimal point: (0.)

- multiply .6875 x 2 = 1.375 left of decimal is 1, write a 1: (0.1)

- drop the 1 and multiply .375 x 2 = .75 left of decimal is 0. write a 0: (0.10)

- multiply .75 x 2 = 1.5 left of decimal is 1, write a 1: (0.101)

- drop the 1, multiple .5 x 2 = 1. left of decimal is 1, write a 1: (0.1011).

- since there is no more fraction, the final answer is (0.1011). Hope this helps.

Hi there,

My name is adieh.have a great day.

I will give a simple example on how to convert your answer into decimal form. Indicated below:

Q: Simplify 1/2-5/13 convert to decimal

Answer:

Step 1: Enter 1/2 by pressing 1>a/b>2.

Step 2: Subtract by pressing - (negative sign or minus sign)

Step 3: Enter 5/13 by pressing 5>a/b>13.

Step 4: Find the difference by pressing**= (equals sign)**

**Step5: Convert to decimal by pressing (change)**

** You can find( change) on the right side of your calculator beside M+ key**

I am suggesting you to visit this website http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/Archive/cal_man_ELW535B_TeachersGuide.pdf

for you to have further knowledge about various functions of your sharp calculator since you are attending a business/algebra class.

Hope it helps.

Thank you for using fixya.

Yes. Pressing the DMS key (two keys above the 8 key) when a result is displayed toggles the result between decimal degrees and degrees-minutes-seconds.

For example, to convert 3.5 degrees, press 3 . 5 = and you'll see 3.5. Now press DMS and you'll see 3 degrees 30 minutes 0 seconds.

If you want your calculator to display the results with 5 decimal digits:

- Open the [MODE] configuration screen.
- On first line highlight [NORMAL], if it is not already highlighted and press [ENTER] to validate.
- Use Down arrow key once to reach the line Float 0 1 2 3 4 5 6 7 8 9
- Use right or left arrow key to highlight the number 5 in the foregoing list (Float 0 1 2 3 4 5 6 7 8 9).
- Press ENTER to validate your choice
- Press [2nd][Quit] to exit the [MODE] configuration screen.

Hello,

Just after you obtain a result in the form of a fraction, press the [F<->D] key to convert it to a decimal number. If you enter the ratio of two numbers as numerator / denominator =, (without using the [a b/c] key) the result will be displayed as a decimal number/

Hope it helps.

Hello,

Turn calculator ON, press MENU if you see no icons. Use arrow key to highlight the RUN application. Press OPTN, press F6 to pan right. Press F3: Prob, then F4:Ran# then EXE to execute.

Each time you press EXE a new random number is generated. You might want to fix the number of decimal digits to less than the 10 digits displayed by default.

By default number generated are between 0 and 1. If you want numbers between 0 and 100 you enter Ran#(100).

Hope it helps.

Hello,

75/100 [=] gives 3/4. Press [S<->D] key to convert to decimal 0.75

0.75 [=] gives 0.75 Press [S<->D] key to convert to fraction 3/4

It can convert radicals into decimal and decimals into radicals.

Hope it helps.

It does. For instance, to get the reciprocal of 4, enter the following sequence:
4 [1/x] (this last key to be found third row down, second black key in). The decimal 0.25 will appear as the result. Convert this, if you want, to the fraction 1/4 by pressing the yellow function key [2nd], then {F<>D] located bottom, far left.
Hope that's what you wanted!
