After you replace batteries, the screen contrast may become too light or to dark. In your case, I suspect it lightened too much.

To darken screen

Press [2nd] key and release it.
Press and HOLD the [UpArrow]
Keep pressing the Arrow key until screen darkens to your liking.

If that does not solve your problem search this website: I have answered countless number of questions on the same subject.

Why is it that small decimal numbers only show in exponents instead of a long decimal number?


The calculator has three display formats for results: Normal, Scientific, and Engineering. It is possible that your calculator is configured to display results in Scientific Format.
Press the MODE button. On the first line, highlight Normal. After that you can use the Down Arrow to move cursor to the second line and highlight FLOAT.

Sharp EL- M332 caluclator- have a 'O' along top line- can't seem to get rid of it- must have accidentally selected something. It is not showing any decimals.


Hold (C.CE) then whilst holding it press (M+) for approximately a second and it will move one place along in the three settings (F, 2 and 0) F shows full decimals, 2 shows 2 decimal places and 0 as yours is set to now round to the nearest whole number. I have just been sat at my desk trying to work this out as my calculator was too set to '0'. Took me reading the 'DEC DET' text with lines pointing at 'M+' and 'C.CE' to finally crack it!

Hope this helps.

You must have used the TRANSFRM application before. It remains in memory and takes over the graphing function from the native OS. You must unload it from memory.

  1. Turn calculator ON
  2. Press the [APPS] button.
  3. Scroll Up (faster) or Scroll down till you see :Transfrm in the list of applications.
  4. Highlight that line and press ENTER.
  5. The new screen invites you to Uninstall or Continue
  6. Press the number key that corresponds to the Uninstall option (1:Uninstall)
  7. Return to your [Y=] editor screen to verify that the style lines have changed to the "normal" ones.
