SOURCE: how do i display decimals on casio fx 115es

The instructions are below the screen. It says Mode arrow and a table of numbers.

If you want to set (use) degrees, you press the MODE key followed by the 4 key. On the top of the screen **deg** will be displayed.

If you want to set RAD or GRAD, similarily, you press MODE followed by 5, or MODE then 6.

However **if you want to convert a result displayed in a particular unit **into other angle units, you press SHIFT MODE then 4 or 5 or 6, whichever is the case for you.

Hope it helps.

Hello,

To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.

Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

SOURCE: Why does it solve in fractions?

The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.

- In MthIO you enter fractions and radicals as you see them in textbook (multiple levels). Calculations are exact and results are generally a mixture of fractions and radicals.
- In LineIO, numbers are entered the old way and all numbers, operations are written on a single line. All fractions and radicals are converted into decimals numbers.

If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].

However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.

To set LineIO press [SHIFT][MODE][2:LineIO]

Yes. Simply enter the fraction and press =. If the calculator is in the MathIO mode it will display the fraction in its simplest form. If you're in the LineIO mode, press the S--D button to convert the decimal to fraction.

Press the [S=D] key to toggle between fractions and decimals. Converting a decimal result to a fraction is not always possible. There may be limit of 10 digits between numerator and denominator.

If the calculator is in the MthIO mode it will always attempt to display the result as a fraction. To convert a single result to decimal, press SD. To have the result always come out in decimal (according to the selected display mode), press SHIFT MODE 2 to select the LineIO mode.

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/Output mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

if you do not want to change your settings There are two ways to foecr calculator to display a result in a decimal 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]

- Before pressing the [=] sign to get the result press [SHIFT] key. thus [SHIFT][=] displays a result in decimal format.
- 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.
- 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.)
- That does not mean that every decimal number can be converted to fractions/radical.

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]

If your calculator is configured to be in MthIO, the fraction that is displayed is always reduced to its simplest form. (The denominator is the smallest possible.)

If you are adding fractions, the result is also a fraction in its reduced form.

If you want to convert a fraction to a decimal number, press the [S<=>D] key.

To set MthIO: Press [SHIFT][MODE] (SetUp) and select [1:MthIO]

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

In LineIO, all results are expressed in decimal format.

If you are adding fractions, the result is also a fraction in its reduced form.

If you want to convert a fraction to a decimal number, press the [S<=>D] key.

To set MthIO: Press [SHIFT][MODE] (SetUp) and select [1:MthIO]

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

In LineIO, all results are expressed in decimal format.

Hello,

**Press [SHIFT][MODE][1:MathIO]**.

When in MathIO, you can obtain decimal results if you press [SHIFT][=] instead of just [=] to calculate.

Also, you can use the [S<=>D] key to toggle from one display format to the other ( Fraction <-> Decimals) or (Radicals<->Decimals).

Hope it helps.

Hello,

To make sure that results are always in decimal format, put a decimal mark (point) at the end of one integer.

ex:**1./2 or 1/2. **or** 1./2.** display as 0.5, so does **1. + 1/2**

To convert from decimal to fraction and from fraction to decimal press**a b/c**

To convert from proper to improper fractions use**[SHIFT][d/c] **

Hope it helps.
