Press "f" then 2. The number you press after "f" sets the number of digits to the right of the decimel point.

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..

The more common name for the 357 is SR44. Other common names you might see are LR44, A76, and S76, depending on the manufacturer. Any of those will work.

### Hoe to I get my hp 12c calculator to show the begin/end format? It did, now when o hit "g" "7" beg or "g" "*' end, can not get to display? Thank you !

Begin mode is obtained by pressing [g][7] and it should then show BEGIN in the bottom line of the display. End mode is obtained by pressing [g][8]. End mode does not not show an indicator in the display because it is the default mode, so if BEGIN isn't showing, then the calulator is in End mode.

I'm doing this from memory because my 12c is at home, but I believe that there is a "fix" key. You need to enter shift-fix-2 (this will set the decimal places to 2).
