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]

To convert a single result from fraction to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select LineIO mode.

Yeah? What do you want with it?Do we have to play good cop, bad cop to make you reveal what you want?

Could be just a fraction 1/5 or a decimal number 0.2

If you calculator gives you a fraction use the [S<->D] to convert it to a decimal number. If it gives you a decimal number, you can convert it to a fraction by pressing the [S<->D key.

Hi,

You are not specifying the brand and model number of your calculator and that makes things more difficult for me. On the Casio calculators (FX-300ES, FX-115ES, FX-991ES) there is key labeled [S to D] which toggles between Fractions/Radicals To Decimals.

On other calculators (Sharp), the key may be labeled F To E.

You should look for a key that has two letters with a two-sided arrow linking the letters.

Why I even try to answer a question that lacks basic information and give the opportunity to the asker to shoot me dead is beyond me.

Anyway, I hope it helps.

Hello,

If a number is displayed as a fraction or a radical (square root or other roots) you change it into a decimal number by pressing the [S<=>D] key, just above the red [DEL] key.

If you do not care for fractions or radicals, you configure your calculator to display only decimals. To do that you press [SHIFT][MODE][2:LineIO].

Warning: If you do that you will not be able to enter fractions or radicals in the natural (textbook display)

Another way to display a fraction or a radical as a decimal is to press [SHIFT][=] to get the result not the [=] alone.

Hope it helps.

Hello,

To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.

Dans ce cas 1/6 is displayes ase 0.167.

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.

you want a line output

Shift > Mode > 2:LineIO or on the graphics one its sometimes 10:LineO etc.

look for something with line in it

Steve :P

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

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)
