How can I easily change my TI decimal places to read 2 instead of 14? and undo it.
Also how can I get my answer to show % instead of dec. Hopefully easy like the diamond key and enter sol.

I don't know about a permanent solution but you can get it to give you decimals with a second keystroke. just hit the diamond key and enter and that will get the calculator to approximate the fraction for you.

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]

### How can i change my calculator so the answer will be in decimals instead of exponents or fraction?

There is a misconception hiding here in your statement. A decimal result on a calculator is often no more than an approximation: Try expressing 1/3 as a finite decimal representation. So, the only exact results that you may get are those displayed as fractions and those with radicals.
Now let us address your question. The calculator has a limited display capability. Any decimal result that is too small or too large to fit in the display window will automatically be displayed in scientific notation (the one with exponents).
If you want exact results, you should set the Input/output to MathIO. Even then, if the expression requires more display space than is available, it will be displayed as a decimal number.

Getting Decimal Answers by Disabling WriteView on the Sharp EL-W516 Calculator

The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors.

At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers.
If you prefer to always get decimal results you need to disable the WriteView display mode. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.
Disabling WriteView

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

NOTE: It is not possible to have decimals as the default answer form when in WriteView mode.

### How do i display a fraction?

Hello,
Press [SHIFT][MODE][1:MathIO].
When in MathIO, you can obtain decimal results if you press [SHIFT][=] instead of just [=] to calculate.
Also, you can use the [S<=>D] key to toggle from one display format to the other ( Fraction <-> Decimals) or (Radicals<->Decimals).

Hope it helps.

### When I divide answers are always given in Fractions. Can I change it to come out in decimals?

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
