Hello,

If you want your decimal numbers to appear with the decimal point, and not in a fraction form, all you have to do is
Press [SHIFT]MODE][2:LineIO].

My personal opinion (if you care to hear it) is that the new TextBook Display is a major improvement in scientific calculators, because you see the link between what your write with pencil and what the secreen displays. Often students are ill-informed about operation priorities and enter their operations as they think it right, but results are wrong.
With the MathIO (texbook display) of the Casio you can spot right away what the calculator will do and hence correct it before it does it.

The other point is the following. If you have a short or long string of operations to do, you can do them all at one go, checking once in a while (on the display) that the sequence of operations is correct. After you finish entering the string of operations press [ENTER/=] key.
If the final result (the one you are seeking) is in a format you do not want, you press the [S<-->D] key to convert it between decimal and fraction representation.

If the result just obtained is needed to carry out further calculations it is more precise to use a fraction than a decimal representation: The fraction is exact, while it decimal representation is approximate.

Hope it helps

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.

Testimonial: "I bought the calculator because it was on sale and I like Casio calculators; not for its fractional abilities. I can easily switch it back now. Thanks"
