School starts in a few days and I decided to try out my calculator. I am not sure what exactly went wrong, but now it won't stop rounding up my answers.
Press the MODE key repeatedly until you get to the "Fix Sci Norm" screen. Press 3 then 2.

Sorry I never got a mail when you asked the question, I guess you've solved it by now...
any for anyone else who may have the same problem..you have fix selected(significant figures)
press the mode button top right, repeatedly until it displays Fix sci norm,
press the number underneath Fix which is probably 1
then press the number of decimal places you would like Between 0 to 9 yours at the moment is obviously set to 0
Sorry for being so late....

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.

Hello,
Use the FIX display format and set the number of decimal digits to be displayed to be 2 o 3 or more depending on your needs. Instructions are on screen capture below. Hope it helps.

I've had this issue
before with my TI-83 Plus. I'm not sure exactly the solution I used, but these
steps progress through the mildest to most extreme methods of fixing the
calculator.
Solution 1: Take the batteries out.
Odds are you've tried
this already, but it bears mentioning.
With the calculator on,
remove the triple A batteries housed in the back. After a few seconds, replace
them and turn the calculator on.
Solution 2: Clear the RAM.
Remove one of the AAA
batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the
AAA battery and then turn the calculator on. The calculator should display the
message "RAM Cleared". Release the [CLEAR] key and then press it one
more time to remove the message.
Solution 3: Reinstall the operating system
Remove one of the AAA
batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA
battery and then turn the calculator on. The calculator should display "Waiting...Please
install calculator software now"
Here is the website to reinstall your OS.
First you'll need the TI-Connect
software.
Solution 4: Remove all sources of power. This is a risky move, but if your
calculator will absolutely not work after you try even reinstalling the
operating system, it might be your last hope.
Remove all of the batteries
including the round lithium battery for 5 minutes. After the 5 minute period,
reinsert all of the batteries and turn the calculator on. Adjust the contrast
if necessary.
