    Is there any way to have it display in decimal on the bottom of the screen automatically.

  • Anonymous Feb 20, 2009

    [SHIFT], [=]
    gives the same result as
    [S<>D]
    I think jaylagirl wants it to display in decimal by default, every time.

  • Anonymous Feb 25, 2009

    your fix does work(thanks) but how can i get my calculator to give an answer in decimal as a default.

  • jaylagirl Feb 26, 2009

    Thanks the Linear I/O solution is what I was looking for... thanks again. This is an awesome service, thanks to all that participate.

Turn it on, hit "shift", "set up", then "2". Puts the calculator in Linear I/O and gives yo decimals! It will stay in this mode 'til you change it.

When you have the answer in the bottom of the screen hit shift then = and that will display it in decimal form.

Changing 80% to a fraction in the lowest term


You have to be careful. 80% is in fact 0.8.
Turn the calculator ON.
Enter the number 0.8
If your calculator is set to Write-View you will see the number displayed as a stacked fraction 4/5. If it is already in this form, press the key marked change with two arrows. The display should show a fraction.

If your calculator is set to LINE, you will see 4r5, where 4 is the numerator and 5 is the denominator.

The key marked change allows you to change displayed result from decimal to fraction and from fraction to decimal. When a number is converted to a fraction, it will always be a fraction reduced to its simplest terms.

How to claculate the remainder of a fraction using CASIO fx-991ES?


Use the fraction conversion features of the calculator.
Near (above) the [S<>D] key that toggles display between fraction/radicals and decimals, there is a marking that reads [a b/c <=>d/c]. Accessed through the [SHIFT] key, this key converts from improper fractions [a b/c] to improper fractions [d/c].
Enter your fraction with the fraction key (the one below the CALC key) and press enter. If the numerator is less then the denominator (proper fraction) the remainder is just the numerator. If the numerator is greater than the denominator the display will show an improper fraction (d/c) or a mixed number [a b/c]. Here a is the integer part and b/c is the fraction part.
So, if you have [a b/c] type display the remainder is b.
If the result is displayed as an improper fraction, use [SHIFT][S<>D] to convert the improper fraction (d/c) to a b/c.

I am using my Casio fx-300MS and have somehow gotten into the display where it puts my answers in exponential form; 5+5 = 1.0 exp10 to the 1. How do I return to getting my answers in standard form?


Display Format

To change the exponential display format, press the [MODE] key 3 times.

Fixed number of decimal places:

Press 1: Scientific Notation: 0

Press 2: SCI: 0

Press 3: NORM

You will then be prompted for NORM 1 or NORM 2. CHOOSE NORM 1


To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]

[=]. This will return the calculator to the following settings:

Calculation mode COMP

Angle unit Deg

Exponential display format Norm 1

Fraction display format a b/c

Decimal point character Dot

Answer is in the form of a fraction


What is the question? Do you want fractions or not?
  • If you want to perform exact calculations (that is with fractions and radicals) you should set the calculator Input-output mode to MathIO. Even with this mode set as default you can still convert the final result to a decimal number. This can be done 2 ways.
  1. Result is already displayed in fraction/radical format: Press the [S-D] key to toggle between the two formats.
  2. Result has not been calculated yed (expression still in command line), then press [SHIFT][=] to ensure it is displayed in decimal format.
  • If you do not want fractions nor radicals (roots) just set the default Input-Output to LineIO
To set one or the other IO modes, do as follows.
  1. Press [SHIFT][MODE] to open setUp and select [1:MathIO] to select natural display with fractions/radicals.
  2. Press [SHIF¨][MODE] and select [2:LineIO]

How do I make a square root into a decimal


If a result is displayed in fraction/radical form, just press the [S<>D] key to convert it to decimal.
If you do not want fraction/radical display, configure the calculator to be in LineIO.
To do so press [SHIFT][MODE] then select [2:LineIO] and no more fractions nor radicals will be displayed.

My calculator will show fractions instead of decimals when doing division. How do I change that? There is a N1 displayed in the lower left corner also...I think that may be the problem


Getting Decimal Answers by Disabling WriteViewelw516.gif on the Sharp EL-W516 Calculator

The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors.

At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers.
If you prefer to always get decimal results you need to disable the WriteView display mode. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.
Disabling WriteView

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

NOTE: It is not possible to have decimals as the default answer form when in WriteView mode.

I try to write a fraction down on my TI-83 calc. But i dont know how to find that function. When i go to MATH and choose FRAC it doesnt do anything even if i type a number down next to it.


To keep a fraction in fraction format (though reduced) you must enter the numerator, press the Division key, followed by a number (denominator).

If you press ENTER, the fraction will be displayed as a decimal number.
However if you use the sequence [MATH][1:ToFrac] peior to pressing [ENTER] the result will be the irreducible form pf the fraction you entered.
Obviously, if you enter an interger number there will not be any fraction display.
Also, if your "number down next to it" means after the [ToFrac], then it is clear that nothing will happen.

Try what I suggest and see if that works.

Changing how the result is displayed


The calculator has two input/output (I/O) modes: MthIO and LineIO.
MthIO is a very nice novelty: it allows one to enter expressions as with pen and paper (textbook display). Results are displayed, whenever possible, as exact values ie fractions and radicals.
MthIO is the default I/O mode of the calculator. If it is not set, you can set it by pressing [SHIFT][MODE] (SetUp) to access a list of choices. Select [1:MthIO].

The other I/O mode is the old way of doing things: every thing is enter on the same level line, while in MthIO you have textbook style templates. In LineI/O all results are displayed as decimal (approximate) values.

To set LineIO press [SHIFT][MODE](SetUp) and select [2:LineIO].

If the displyed result is fresh you can toggle between decimals and fractions/radicals by pressing the [S<=>D] key.
Even if you are in MthIO you can force the (final) result into decimal display format by pressing, NOT the = sign, but [SHIFT][=] .
