HP 41CX Decimal Point restore Message #1 Posted by Joseph Banki on 22 Apr 2011, 7:06 p.m. Hi; After replacing the batteries, the decimal point became a comma, and can not restore it. Also I always used 4 decimals before and that does not come back either. I have the Basics Volume 1 only, and Volume 2 or 3 (?) handles that. Could you help? Thank you Joseph Banki enj-banki@sbcglobal.net 281-788-4007

Re: HP 41CX Decimal Point restore Message #2 Posted by spb on 22 Apr 2011, 7:52 p.m., in response to message #1 by Joseph Banki SF 28 Flag 28 controls the behaviour; when set the separator between the integer and decimal part is a period and the digit separator for the powers of three (if set) is a comma, and when cleared the semantics are reversed.

Re: HP 41CX Decimal Point restore Message #4 Posted by Dieter on 23 Apr 2011, 7:07 a.m., in response to message #1 by Joseph Banki That sounds more than strange. Replacing the batteries definitely does not affect the display setting or anything else of interest. Maybe something happened that put the 41 in an undefined state. If the calculator does not hold any important data I would recommend a master clear: Turn off, hold down the backspace key (left arrow), press ON and release all keys. This will reset and clear the whole unit, all data is lost and the calculator returns to its default settings. Including the display (FIX 4, decimal point, thousands separators on). So 12345 will display as "12,345.0000". The decimal separator is controlled by Flag 28. Use CF 28 for a comma or SF 28 for a point (= default). The thousands separator is controlled by Flag 29. Use CF 29 to turn it off or SF 29 to turn it on (= default). The display format is set with FIX, SCI or ENG and the number of digits you want. You say Fix 4 "does not come back either". So you press FIX 4 and nothing happens?!? In this case it's definitely time for a reset. Dieter

As I posted to SPB, the calculator works properly now, decimal points, thousand separator and digits. Appreciate your help.Thanks again Joseph
