Re: HP 20b logarithm error Message #6 Posted by Karl Schneider on 5 Jan 2009, 2:58 a.m., in response to message #1 by Michael Andersson
Michael --
Please read the thread that Thomas Klemm linked. You will find that the common-logarithm errors were present on an earlier firmware version, which, I would say, ought not to have been released for commercial sale.
Each attendee of the HHC 2008 event in Corvallis received a new HP-20b. Mine has a later serial number CNG83300019, and it does not exhibit the flaws that yours does.
In my opinion, you're entitled to an exchange. Gross math errors like those are unacceptable.
