"FIX" mode is the number of decimal places, When you say Fix-0 it will truncate the decimals.
Either set model FIX-4 or FIX-5 or better still, just regular COMP mode.
Shift-clr-2 (mode) should set it back to defaults.

My calculator will give me an answer in scientific notation. How do I change it to decimal form?

To switch out of scientific notation, press SHIFT MODE then select Fix or Norm.

Be aware that the calculator will switch to scientific notation anyway if the magnitude of the answer is too large or too small.

HOw to change FSE code on Sharp Advanced D.A.L. EL-531X

Hi there,

To change the FSE code on your SHARP calculator press SETUP and choose 0. FIX means that it shows you all the decimal places. SCI is scientific notation, ENG changes the scientific notation in groups of 3's. NORM1 and NORM2 are your normal number ranges, however norm2 starts from zero and anything negative will be written in scientific notation.

You want to change the display mode. Press SHIFT MODE. Then press 6 and a number specifying the number of digits after the decimal point for fixed decimal notation, or 6 and 1 or 2 to specify one of the floating point modes.

I want to remove the word fix from the top of the calculator

You've got the display set to fixed decimal notation. To change it, press SHIFT MODE 7 to switch to a scientific notation or SHIFT MODE 8 and then 1 or 2 to switch to one of the norm display modes.

norm1 switches to scientific notation if the magnitude of the number is less than 0.01 .
norm2 switches to scientific notation if the magnitude of the number is less than 0.000000001 .

How do i take off scientic mode just a regualer:

Press SHIFT [SETUP]. You can select FIX for fixed-decimal or NORM for normal display. For FIX the calculator will prompt for the number of digits. NORM gives you two choices: 1 will display numbers of magnitude less than 10E-2 in scientific notation, 2 won't switch to scientific notation until the magnitude drops below 10E-9.

Trying to get calculator to display in scientific notation

Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.
You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.

If you do not want fractions nor radicals set the default Input/Output format to LineIO.
To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.

Press [SHIFT][MODE][6:Fix] and press a numbetr between (0--9). The number you select will be the number of decimal places your results have.
However if a result is smaller than 0.001 it will be in scientific notation.

Hope it helps.

I am trying to calculate a problem using scientific notation but it is not giving me the correct answer and my calculator is set to 9 dec places the equation is 1.9x10^10- x 453.6 / 163871 I keep getting...

Your notation expression contains an extra symbol ( either the - or the second x).
If I enter
(1.9x10^10)x453.6/163871 I get 5.262148845 x 10^7 about 5.3 x10^7
If I enter
(1.9x10^10 - 453.6)/163871 I get 1.159 x 10^5.
Your result is off by a factor of 100 to 10000.
As to the scientific display mode, you set it by pressing [MODE][->][SCI][ENTER] [2nd][QUIT]. You can leave the Float option to 9 digits if you want.

Hope it helps.
