Question about Casio FX-115ES Scientific Calculator
When you have a fraction output, press the [S<->D] key to convert to decimal, the same key to convert from decimal to fraction. Beware that fraction results are exact, while decimal values are approximate.
However if you cannot stand the sight of a fraction, there is a way to get rid of this type of output.
Here is how you do it.
[SHIFT][MODE][2:LineIO]. All your results will be in decimal. However you will lose a lot of functionalities, such as calculating the logarithm in any base, manipulating radicals.
My advice, if you allow, is to activate the [SHIFT][MODE][1:MathIO] and press the [S<->D] whenever you want a result (be it a fraction or radical) in decimal format.
Hope it helps.

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
