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 Casio fx-115 ES Natural Display is solving 21.9 in a fraction when I put the calculator in scientific mode.... Why?


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.

Why does the answers goes to fractions


In MathIO mode the calculator tries to display answers as fractions whenever possible. You can convert a single result to decimal by pressing the SD key just above DEL. To have all results come out in decimal format, press SHIFT MODE 2 to select LineIO mode.

I cannot find how to change my answer display to a decimal instead of a fraction on a Casio FX-115ES. I am working with financial formulas and need decimals! Anyone???


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]

Casio fx-300ES Default answer readout?


Hello,

Generally, MathIO gives results in fractions or radicals. But sometimes it does not. I tried multiplying or dividing fractions or radicals by integer numbers, and once in while I got a decimal result and was unable to cast it into a fraction or a radical. I was not able to find the pattern.
In lineIO you only get decimal results.
What can one tell you that you cannot determine for yourself? If you appreciate the functionalities of the MathIO, it seems like an insignificant price to pay to press ONE button to switch between displays. It needs to be done ONLY once, for the last result one wants to record.
Your calculator, Your rules. But sometimes one cannot eat the cake and have it too.

Problems with fractions on the Casio fx-115es


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.
