All that can be fixed if you reset the calculator.

Turn on the calculator if not already on, push "Shift" "9", which gets you to 3 options. Push option 3 for "All". Then "=" and "AC". That should reset the machine.

If you like your answers in decimal (all the time), such as 5/8=0.625 and not 5/8 then push "Shift", "Setup", "2". Or... just push the "S<=>D" key.

Apparently your problem has a complex (non-real) answer. By default the calculator works with real numbers and gives this message when the solution is not real.

You can change this by pressing the MODE button, down-arrow to the "REAL" line, right-arrow to one of the two complex display modes, then press ENTER and 2nd QUIT to save the change.

If you still have problems, could you post an example that produces this message?

<span><b>Getting Decimal Answers by Disabling WriteView<img src="elw516.gif" /> on the Sharp EL-W516 Calculator<br /><br /></b>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. <br /><br />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. <br />If you prefer to always get decimal results you need to <b>disable</b> <b>the WriteView display mode</b>. 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.<br /><b>Disabling WriteView<br /></b><br />Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.<br /><br />There are now two options: 0: W-VIEW, and 1: LINE<br /><br />Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.<br /><br />To return to the WriteView display, go through the steps above but press 0 for W-VIEW.<br /><br /><b>NOTE</b>: It is not possible to have decimals as the default answer form when in WriteView mode. <br /></span>

No need for such a program. You can specify the angle unit for a calculation regradless of the angle unit currently set as default.

__For the TI Nspire with Touchpad__.

Calculate the sine of 30 degrees.

Press the trig> button next to = on the left side of keyboard.

Select sin and press ENTER

Type in 30

Press the key with the question/Exclamation marks.

Use right arrow to highlight the degree symbol.

Press ENTER. No need to close parenthesis.

The answer is displayed as 0.5.

To enter an angle in radian (regardless of the angle unit set as default.

Do as above to type in the function

Type in the angle.

Press the small button marked with Pi and arrow (To the left under the EE button)

Use the arrow to highlight the small superscript r.

Press ENTER

Make sure you're angular mode is set to radians, not degrees. With the default window range, sin(x) in degrees is virtually indistinguishable from zero.

To change the angular mode, press MODE, down-arrow twice, left/right-arrow to highlight Radian, ENTER to set it, and 2ND [QUIT] to exit.

Once a result is displayed you can convert it from fraction to decimal by pressing the [S<=>D] key.

Alternatively, press the keys [SHIFT][=] to get a result instead of just [=].

You can also configure Input output mode of calculator to LineIO and you will not get fractions nor radicals, just decimals.

To set LineIO as the default IO mode press [SHIFT][MODE][2:LineIO].

Hello,

There are several ways you can extract decimal numbers from this fine calculator.

**In MathIO Mode**

1. Once a fraction or radical is displayed press [S<=>D] button to convert it to decimal. Pressing it again restores the fraction or radical display.

2. Instead of pressing the [=] key to obtain a result, press [SHIFT][=]. The result will be displayed as a decimal number.

**In LineIO**

If you do not care for exact calculations with radicals and fractions, just change the default mode from MathIO to LineIO. To do so

press [SHIFT]{MODE][2:LineIO]. In this input/output mode all results are decimal.

Please be informed that with this mode you will not be able to access the formula templates that allow you to enter fraction as you see them in textbooks (the natural display format). You lose other neat functionalities also.

As a suggestion, if you like the natural display for input keep it as default, and press [SHIFT][=] to display decimal results or [S<=>D] to convert display to decimal format.

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.

Hi,

I I understand correctly, you want your results to be displayed with 7 decimal digits, right?

Pressing the MODE button/key will take you to the first page of your calculator default settings.

Scroll down the list to Display digits where it says on the right FLOAT 6

Press the right arrow to on your directional button, a list opens up showing all the options available for you.

Then you can select FLOAT 7 Pressing ENTER then ENTER will validate your new default stting and take you back to the HOME screen.

If instead you are interested in FIX 7 you can so choose.

if you press the |mode| button (at the top right of the calculator) until you see Deg Rad Gra on the screen (I believe 3 presses of the mode button) and just hit the number below the rad option on the display. This will permanently change it to radian mode until you repeat this step, or clear the memory.

There is also a way to change to radian mode for just one operation if you will be mostly using degrees for example

at the bottom there is a DRG> as a shifted function. I would just recommend changing it in the way I initially outlined as there is less room for error when making calculations.
