As I added on to the previous solution on the other problem.


"Okay, I did what the best solution did and worked with it.

"1. press 2nd F (left top corner)
2. ENG/FIX (the button next to 2nd F)
3. press 0 (if you don't want calculator to round off any decimals)"

In order to get your exact value of pi, in step #3, instead of 0, press the decimal [ . ]
This should give you no decimals when entering a number and give you 3.141592654... when you input pi.
Hope that works/helps."

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.

SOURCE: sharp el506d calculator has the decimal in the wrong place.

Try pressing the FSE button to switch between Fixed, Scientific, Engineering, and Normal displays. When in Fixed display, you can use <2ndF> < TAB > then enter a number from 0 to 9 to choose the number of decimal places in that display. To reset EVERYTHING to factory defaults: With the calculator off, press and hold these three keys: <2ndF> < ) > < ON/C > then release all three. The calculator will go through a series of tests (it takes a few seconds) and then be at its factory defaults. I have uploaded the manual for this calculator at www.theusermanualsite.com.

I have a canon F-502G and my number 9, pi, decimal sign and X(OCT) don't work. Please help! I've tried everything and I don't know what to do. Also there is OCT on my screen.


Your problem is that the calculator is in Base N calculator mode (Octal, base 8). only the keys 0 to 7 are active. Change the mode to Decimal (base 10) or reset it completely, and your calculator will come back to life.

How do I stop calculator from rounding up?


Hi Carol,

There are switches at the top just under the screen called the "Rounding Switch" and the "Decimal Point Selector Switch".

With the rounding switch you can select rounding up or down, but you may also want to use the second switch to show more digits after the decimal. Put it in the "F" position to show all decimal places. When it is in the 0, 1, 2 positions, it strips off and round the numbers.

Here is the link to the manual as well, look at the section detailing the "Decimal Point Selector Switch".

(You will need an Adobe Acrobat Reader to look at the manual.)

Hope this will help you. http://downloads.canon.com/cpr/software/calculator/P23-DHV-(USA-HWB).pdf

Convert a decimal into a fraction


Conversion is not always possible. If a decimal result has just been found and displayed, pressing the [a b/c] fraction button may convert the result still in answer memory (ans) to a fraction. But if you alter the value of answer memory and type in the (approximate) decimal value that you copied from the screen, you may not get your correct fraction.

HP 12 C display does not show entire numbers. How do I fix?


If you mean it is not showing everything after the decimal point, you can change that by pressing the [f] key followed by the number of decimal places to display. For example, to restrict it to 2 places, press [f][2]. If you want to see 4 places, press [f][4].

To show all possible decimal places, use the sequence [f][9].
From the manual (http://www.hp.com/ctg/Manual/c00363319.pdf):
"To display a different number of decimal places, press f followed by a digit key (0 through 9) specifying the number of decimal places. In the following examples, notice how the displayed form of the number inside the calculator - 14.87456320 - is rounded to the specified number of digits."


25096057-rvrejqbjq4zuw4cbinsyjvsy-5-0.png "Although nine decimal places were
specified after f, only eight are
displayed since the display can
show a total of only 10 digits. "
The standard display format, plus the specified number of decimal places, remain in effect until you change them; they are not reset each time the calculator is turned on. However, if Continuous Memory is reset, when the calculator is next turned on numbers will be displayed in the standard display format with two decimal places
shown.
If a calculated answer is either too small or too large to be displayed in the standard display format, the display format automatically switches to scientific notation. The display returns to the standard display format for all numbers that can be displayed in that format.

On my Canon F502G, my a b/c button does not work from decimals to fractions. It will only go fractions to decimals. Is there something I can do to get it going?


If you convert a fraction to decimal and then just after do the opposite it will convert from decimal to fraction. But if you do some other calculations in between it may not do it.

I have the Canon LS-100TS Calculator. I am showing 9 decimal places, I only want 2. I seemed to have adjusted on its own. Eg: 2x2=4.000000000 I would prefer 2x2=4 (i.e only showing decimals when...

If that doesn't work repost.

Decimal placing


Above the feed button is an area for controlling the decimal placement. By leaving the slider on +, you have to manually put the decimal in.
0 - Means no decimal will be placed.
1 - Put it one place to the end. Ex: 4132.5
2 - Will make it read 413.25
3 - Will be 41.325

And so on.

I want two decimal points to show


I called Canon customer support. There is a tiny reset button on the lower back area of the calculator. Simply stick a small object in there to reset the calculator and you should be as good as new! Worked for me!
