# Display a decimal point

I changed the battery in a HP 12c calculator. It now displays a comma instead of a decimal point. What is the function to display a decimal point? Thanks Muddman

Turn the calculator off, then press and hold down the .(decimal key) while you press the on button. Doing so again sets the calculator to use the original digit separators in the display

### Need to change my display from a comma to decimal

I don't know which particular calculator model you have, but for an HP-12C, the manual says the following:
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.

### 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,

### 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

### HP 12c cALCULATOR

It is not calculating because your decimal point and the digit separator (that's the comma which automatically displays for every group of 3 digits) got messed up. To clear, turn the calculator OFF, then press and hold down the dot (that is the decimal point symbol) key while you press the ON key..

### Display shows comma in place of decimal point?

To change the ´comma´, make sure the calculator is switched to off, press (.) key and maintain, switch the calculator ON. This operation changes dot to comma and vice-versa.
