Wrong format for numbers displayed in HP 12C

Somehow the display of numbers in my HP12C has been changed to show numbers like the following
200,00
how do I get it back to the standard format that would show
200.00 only - i.e. there is a comma where there should be a decimal point
thanks

It's been awhile since I used one of these but there should be a decimal function on the keys. Make sure you put a 2 in there before pressing it and it should display the format using 200.00

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.

HP12c seems to not have enough room for numbers BEFORE the decimal point. I try to enter the number "85" and all that will show up is the 8.000000000


Initial Setup

One adjustment is important before we get started. By default the 12C displays only two decimal places. This is not enough. Personally, I like to see five decimal places, but you may prefer some other number. To change the display, press "F" and then the number of decimal places you wish to display. I would press "F 5 " to display 5 decimal places. That's it, the calculator is ready to go.
You need to hold the "F" key.---------

    1. Press and release the gold PREFIX key (f).
    2. Press the number key for the desired number of decimal places (0 through 9).
