Hello,

Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.

To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.

Thus [SHIFT][MODE][1:MathIO].

Hope it helps.

SOURCE: how to change or put math mode without fractions

I am not sure what you want because the mathIO mode IS THE ONE THAT DISPLAYS results as fractions.

You have two display modes: MthIO (with fractions, radicals) and LineIO (with decimals). Which one do you want?

To set MthIO press [Shift][MODE][1:MthIO]

To set LineIO, press [SHIFT][MODE][2:LineIO]

Concerning the scientific display mode.

Decimal numbers can be displayed in various formats, Fixed,Scientific, and Normal. If you do not want scientific display of results, just set the mode to Fix(ed) and specify the number of decimal digits. However if a number to be displayed (a result) is too small or too large IT WILL BE DISPLAYED in scientific format regardless of the mode you selected.

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.

If the calculator is in the MthIO mode it will always attempt to display the result as a fraction. To convert a single result to decimal, press SD. To have the result always come out in decimal (according to the selected display mode), press SHIFT MODE 2 to select the LineIO mode.

I had the same problem with my casio fx-991ES calculator, i tried initializing the calculator by keying in shift9(CLR)3(all)=(yes) but that didn't fix the display,so i opened the calculator and removed the battery for about 5days then put the battery back guess what the display started operating well! no more inverted display or numbers.if initializing the calculator does not fix the problem,take out the battery for some few days then put it back in that should fix the problem.cheers

To convert a single answer from symbolic to decimal, press the S--D key (just above the DEL key). To have all answers come out in decimal format, press SHIFT MODE 2 to switch to the LineIO mode.

I would take it apart and see if they installed the display upside down. I wouldn't think the wires would be long enough to do this, but maybe that is the way it is laid out.

Good luck.

Good luck.

Are you serious?

No calculator purchase should be solely based on such a trivial matter.

But if you are looking for a very good scientific calculator, I would suggest the new Write View EL-W506/W516/W546 calculators by Sharp, or the FX-115ES/991ES Natural Display by Casio.

With these calculators you can see what you enter displayed as in textbooks. Naturally, they all do coordinates conversions from Polar to Rectangular and from Rectangular to Polar.

Hello,

There is something missing in the formulation.

Any way you cannot calculate it directly on this calculator.You need to use the formula

**log_5 (a)= ln(a) x log_5 (e) **a is a positive integer

where** log_5** means log in base 5 (my notation for the function)

**e** is the base of the natural logarithms (e=2.71928 )

**ln** is the natural log function

To obtain a more accurate value of e, calculate e^(1)

Here are some values of log(e) in different bases (for you to play with)

log_2(e)= 1.442695041

log_3(e)=0.9102392266

log_4(e)=0.7213475204

log_5(e)=0.6213349346

log_6(e)=0.5581106266

log_7(e)=0.5138983424

log_8(e)=0.4808983470

log_9(e)=0.4551196133

log_10(e)=log(e)=0.4342944819

If you have to use log in bases other than 10 or e, you will need a claculator that does that at the touch of a button. Some calculators that handle these calculations are the Casio FX-300ES, FX-115ES,FX-991ES, those called Natural Display, or WriteView(Sharp) or Textbook display.

Hope it helps.

Hello,

This calculator transforms every radical into a decimal number. It does not perform exact calculations with radicals. For that you would need a Casio FX-115ES or FX-991ES (Natural Display).

Hi,

If you cannot find it, buy an FX-991ES. It is solar-powerd and it has the natural text-book display, which is a novelty in calculators.

I know that Staples carry the FX-991ES.

Hope it helps.

Hello,

Sorry the calculator handles fractions but not radicals. You may be interested in the newer Casios FX-115ES, or FX-991ES, (Natural display).

*It handles a lof more that radical and fractions*.

Hope it helps.
