To remove the comma, turn off the calculator. With it turned off, push and hold down the [ON] key. While still depressing the [ON] key, push and hold down the decimal or [.] key. Now you should have them both held down. Now, release ONLY the [ON] key.

To remove the "c", push then release the [STO] key. Then push and release the [EEX] key.

### My HP 12C is displaying with a comma rather than a decimal. I don't know how this happened and don' t know how to rid of the comma and return to a decimal. Please help.

Turn the calculator off. Press and hold down the decimal point while you press ON. The digit separator and radix sign will flip each time you do this.

### Cannot get rid of comma

It depends on the purpose of your trying to get rid of the comma. If the decimal mark (radix mark) is the comma, you can change it to the dot. If you just do not want to have the 3-digit separator, maybe you should get used to it, or buy another calculator.

To switch the radix (decimal) mark
Turn the calculator off, then press and hold down the [.] (dot) key while you press [ON]. Doing so again sets the calculator to use the original digit separators in the display.

### When the calculator is turned on, the display reads 0,00 and then in the below right side there is a letter C. How do I clear this?

If the C indicator is displayed it reminds you that interests are compound interests. It it does not show, interests calculated are simple.
To toggle between compound and simple interests, press the key sequence [STO][EEX].

### I just replaced the batteries in my HP 12C calculator and when I turned it back on the display looks like this 0,000. How do I get the display to show decimals instead of a comma?

Hello,
Here is what the manual for the HP 12C Platimum financial calculator says on page 17 of 275

Digit Separators
As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory — or after Continuous Memory is reset — the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display a comma for the decimal point and a dot for the three-digit separator. To do so,
turn the calculator off, then press and hold down the [ . ] key while you press [ON] Doing so again sets the calculator to use the original digit separators in the display.

Hope it helps.

### When I turn my 12c on it has a comma instead of a period.

Hello,
The comma is a three-digit separator that appears if number with many digits are displayed ( millions, billions). Since it is a financial calculator designed for money calculations, the comma can be helpful.
There is nothing in the manual that suggests that the three-digit separator can be removed. It can however be replaced by the point as in European Countries (especially France) where the decimal mark is the point and the three-digit separator the comma.

In short. I do not think you can get rid of the comma.

Hope you can learn to live with it.

### Wrong format for numbers displayed in HP 12C

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
