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.

I need to increase the decimal places displayed on my sharp el 738 calculator. Please help......


From the manual PDF http://www.yorku.ca/ntahani/ADMS3530/EL738_OM.pdf
(page 8 and 9)

decimal places:
set up - 0 - 0 - (tab) displays DIG(0-9) select a number from 0 to 9 decimal places

significant digit:
setup - 0 - 0 - (SCI) displays SIG(0-9) again select a number from 0 to 9 to set...0 sets a 10 digit display

the floating point FLO_A and FLO_B is a nice little chart so i'd advise downloading the PDF if you need to set those :)

How do I program tax rate into my calculator?
Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]


Printing models (except HR-8TE):

1. Have calculator in "print" mode
2. Press [CA]
3. Hold [SET/%] key for about 3 seconds
4. Input the tax rate
5. Press [TAX+]
6. Press [SET/%]
^Top I am having a problem registering the ClassPad 300, it keeps telling me my product key is wrong.
Enter only the numerals, not the letters.
^Top What features do our calculators have?
The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here
^Top What is the [F CUT 5/4] switch or [DEC] F, 0, 2 button for?
The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].
The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.
The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.
^Top What is the [5,4,3,2,1,0 ADD (2)] switch used for?
This switch is used to determine how many decimal places your answer is displayed in.
ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.
^Top Why do I get 111.1111... when I calculate 100+10%?
This is a markup on price procedure. The formula is as follows:
Markup%=(Markup Price-Cost)/(Markup Price)
^Top Why do I get the wrong answer when doing a percent calculation?
Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]
^Top What tests are calculators permitted for?
AP Calculus requires a graphing calculator.
Any graphing or scientific calculator is permitted on the following as long as it does not have a QWERTY keyboard, electronic writing pad or a pen-input/stylus-driven interface:
PSAT/NMSQT, SAT I
SAT II Math, IC & IIC

SETTING UP THE DECIMAL ON NEW 210 TM


Set the +43210F switch to + (or 2).
On some models it is A43210F, then use A (or 2).
+ mode will let you enter numbers (monetary) without the decimal point and assumes cents; 2 mode will just round to 2 decimals, but you must enter the decimal.

My calculator has a funny format


Try pushing and releasing [f], then [4]. This will give you 4 decimal places. (It follows that if you want 5 decimal places, push 5 instead of 4, etc). If that doesn't work, you can try taking the batteries out and putting them back in which should reset it to 2 decimal places, then set it where you want it following the above.

If it continues to malfunction I suggest taking the batteries out for 24 hours to allow a static discharge. This will lose anything you stored in the calculator, setting it back to how it came from the factory.

Reset?


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.
