I have a casio fx-300es, can't seem to figure out how to change it so myu answers come out in decimal form instead of as a a fraction.

To convert a single value between the symbolic and decimal formats, press the S--D key (above the DEL key). To have all results come out in symbolic form press SHIFT [MODE] 1 to select the MthIO mode.

Be aware that the calculator cannot display all values in symbolic form.

To convert a single value from symbolic to decimal, press the S-D key (just above the DEL key). To have all results come out in decimal, press SHIFT MODE 2 to switch to the LineIO mode.
You can download the manual and the appendix here.

Hi suebie50

Have a great day.

To change the output to decimal form, you can do the following:
Go to Math mode, then SHIFT, MODE (set-up), 2 (lineIO).
The answer will show in decimal format.

You can also use this website whenever you have further questions in using you calculator:

Hope it helps.

Thank you for using fixya.

To change a displayed result into a fraction, press the [S=D] key.
To force a result to be displayed as a decimal number before it is displayed, press [SHIF][=] instead of [=].

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.

Press SHIFT MODE 2 to select LineIO mode. Now all results will come out in decimal form.

Press [SHIFT}[MODE] to enter (SETUP). Select [2:LineIO].

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.

Hello,
Since you bent on deactivating the very features that make your calculator so versatile and so powerful, here it is.
Press [SHIFT][MODE][2:LineIO] and you will see no more fractions, nor radicals etc. You asked for it.
Hope it helps.
