Subject: bug#16706: emacs 24.3.1; calc/A command
Date: Mon, 10 Feb 2014 06:15:07 -0500

calc - single variable statistics tells me:

   Another commonly used mean, the RMS (root-mean-square), can be
computed for a vector of numbers simply by using the `A' command.


So:

I believe the RMS value for the vector [21 23 25 25] is 23.5584379788.  (RMS means ‘the root, of the mean, of the square — so 

<ret>
vM*
uM
Q

(returns that value)


A returns
47.1168759576


q1:  How do I figure out what A is doing?

q2: Isn’t this wrong?

Thanks

Here’s the standard form for an error report: (the above just seemed cleaner. Maybe not.)
23.5584379788  

his bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

M-x calc
'[ 21 23 25 25 ]
<ret>
vM*
uM
Q

'[21 23 25 25 ]
A

leaves
2:  23.5584379788
1:  47.1168759576

on the stack.  Shouldn't A return 23.5584379788?
