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

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.

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

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..

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.
