Conversion is not always possible. If a decimal result has just been found and displayed, pressing the [a b/c] fraction button may convert the result still in answer memory (ans) to a fraction. But if you alter the value of answer memory and type in the (approximate) decimal value that you copied from the screen, you may not get your correct fraction.

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]

For converting answers in decimal to fraction or fraction to decimal there is a S<->D key above delete key.If the answers is in fractional form press this key and it will be converted to decimal form.

You can convert between Standard Form (with fractions and pi) or
Decimal form by using the "S<->D" button. Use Mode 1 if you
mostly prefer fraction answers and you can use the SD button to convert
to decimal or use Mode 2 if you mostly prefer decimal answers and use
the SD button to see the fraction.

I hope this helps and good luck!

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.

You can always convert a fraction to a decimal. The reverse may not
always be possible. Look at the example on the screen capture.

You may be lucky and recover a fraction you have just converted into decimal format, but you cannot just write 0.333333333333 and expect the calculator to convert it to 1/3: The true fraction 1/3 has an infinite number of 3's after the decimal mark.

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
