3.89 is not a whole number. There may be some other characters displayed after the 89, such as *10^(-2), or [space] -2

SOURCE: decimals

This is an easy one and happens often. Simply depress the orange "f" key and then select how many decimal points you want on the numeric keys. For example, for two decimal places you would push "f" 2. I usually keep mine on 3, but you can take it from here.

Does not register decimal places at times

Some calculators, and spreadsheets, do not display decimals when your answer is a whole number, unless you specifically set it to a certain number of decimal places.

Good luck,

When you are dividing two whole numbers but you need the answer to be in decimal form, how many numbers after the decimal need to remain especially when there many

It depends on what you need. If you divide 100 by 3 you'll get 33.333333333333333333333333333333 and a lot more 3's.
If you need it to be 2 decimals behind the comma your answer will be 33.33 if you want it to be 3 decimals you'll just end up with 33.333 etc. etc.

So it completely depends on what you need to calculate.

I don't know if maybe my calculator has a function turned on that rounds the answer to a whole number? But here is an example: 106 x 6.32 = 670 according to my calculator, which is wrong. The real answer...

Your calculator is set to display no digits after the decimal point. To change this, you have two options: press 2nd [SCI/ENG] then select "FLO" for floating decimal or press 2nd [FIX] then select the desired number of digits after the decimal point (or F for floating).

Everytime I put decimals into my calculator, it just rounds the answer to the nearest whole number.

Increase the number of decimal digits in display.
  1. Press [SHIFT][MODE] to access the {SETUP)
  2. Enter the number (6) corresponding to option [6:FIX]
  3. In screen that is displyaed, enter the number of decimal digits you want (2, 3, or 4). If you enter 0, all decimal numbers will be displayed as integers (rounded). If you enter 9, you will have long numbers but that is hardly ever necessary.

Different answer fro my TI-89 AND MY tI-81

Your TI81 can only perform numerical calculation: It always give uour numbers. The TI89, a more sophisticated calculator, can of course do numerical calculation, BUT ALSO symbolic ones. You ask it for the derivative of sin(x) and it will give you cos(x).
Anyway, if you want a decimal result for you calculation above one of the numbers must have a decimal point (instead of writing 2PI write 2.PI.

The TI 89 can do exact calculations. But if you want approximate results any number in the sequence of operations must have the mark of a decimal. Numbers without decimal marks are considered integers, Integer numbers with a decimal mark are treated as floating point numbers ( meaning decimal).

Hope it clarifies things for you.

Can not get nothing but fractions for answer

You have to set how the calculator handles numbers. To do this follow these steps: 1. Press the 'MODE' button. This brings up the calculator's main settings page. 2. Scroll down until you reach a field titled 'Exact/Approx...'. This is the setting for how the calculator handles numbers, whether it will show the exact answer (which is usually in fraction format) or whether it will show an approximate number (which will be in decimal format). 3. Press the right arrow which will bring up the options for that setting. You must now choose between three ways of handling numbers: -'1:AUTO' will determine which type of answer the calculator will give based on what numbers you want it to calculate (e.g. if you want an answer in decimal format just add a decimal somewhere in your problem). -'2:EXACT' will automatically display all answers in either whole number format or in fraction format. -'3:APPROXIMATE' will automatically display all answers in decimal format. 4. After you have selected one of those options pres enter one more time to get out of the 'MODE' dialogue and return to the 'HOME' screen. Now try a problem and see what happens. Personally I like using 'AUTO' because then I don't have to keep returning to 'MODE' when I want either or. Hope this helped, I had the same problem when I first started using the TI-89.
