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]

While using Casio fx-300ES , I am unable to get answers in decimals. For eg. 3/10...should give 0.3, but the answer is again displayed as 3/10. any way to solve this issue?


The calculator has two Input/Output modes: MathIO and LineIO.

LineIO
LineIO is the old way of entering numbers in calculators and results are always displayed as decimal numbers. Some calculators have a fraction feature and would convert a fraction to a decimal number and back.

MathIO
In MathIO you enter expressions as you would by hand or as you see them written in textbooks.
In this mode, results are by default displayed as fraction or fractions/ radicals.
Conversion
To convert the fraction/radical to decimals you just press the [SD] key. If you press again you cycle through all the available display formats.
So you can (if you want) use the MathIO to manipulate expressions and convert only the last result to decimal. By the way, fractions and radicals are generally more accurate than their decimal representations.

SetUP
If however seeing fractions and radicals is too painful, just set the LineIO as your default mode. To do so press [SHIFT][MODE] to open (SETUP), then select [2:LineIO]

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.

When dividing the display outputs the answer in fractions but I want the default to display in decimal


If the result is already calculated and displayed, press the [S<=>D] key It will convert a fraction or radical to decimal. This is always possible. If the result is decimal it may be converted to a fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

I cant find how to make my answer in fraction?! please help.


The default Input/Output mode is MthIO. In this mode result may be fractions or radicals or a mix of both.
To set this mode Press [SHIFT][MODE] to enter the (SETUP) screen, then select [1:MthIO]

There is a limitation on how many symbols can be displayed on the screen. If there is not enough space to display the result as a fraction, the calculator will use decimals.

There is a key that can toggle the display from fraction/radicals to decimals. That is the [S<->D] key.

Keep in mind that while you can always convert a fraction/radical result to a decimal one, the reverse may, under ceratin circumstances , not be possible.

How to get answer in decimals instead of fraction


if you do not want to change your settings There are two ways to foecr calculator to display a result in a decimal format.
  1. Before pressing the [=] sign to get the result press [SHIFT] key. thus [SHIFT][=] displays a result in decimal format.
  2. If a result is already displayed and it is not in decimal format (fraction or radical) press the [S<=>D] key to convert it to decimal.
  3. The [S<=>D] key toggles between formats (fraction/radical to decimal and from decimal to fraction or radical depending on the format used in calculation.)
  4. That does not mean that every decimal number can be converted to fractions/radical.
If you want to have all results in decimal format you can configue your calculator to always do so. All it takes is to set LineIO as the default Input/output format.
Press [SHIFT][MODE] to access (Setup) and select [2:LineIO].

Just in case you want to revert to the other IO mode (MthIO)
Press [Shift][MODE][1:MthIO]

Answers in decimals


The calculator has two Input/Output modes, MthIO and LineIO. In MthIO the results are displayed as fractions or as radicals or a mixture of fractions and radicals. What it means, is that in MthIO the calculator does exact calculations. Radicals in denominators are gotten rid of by rationalization, fractions are reduced to the same denominators before addition or subtraction. Fractions are reduced to simplest form.

In LineIO all results are displayed as decimal numbers.

If a result is exact (fractions and radicals) it can be changed to decimal form by pressing the S To D key, the one above the DEL key.

MthIO is the default IO mode. To set it, press SHIFT MODE and select 1:MthIO. To set LineIO as the IO mode, press SHIFT MODE and select 2:LineIO

When I divide answers are always given in Fractions. Can I change it to come out in decimals?


To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button
2) Press the "MODE/SETUP" button
3) Press the "2" button
This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal
