@kindex m N
@pindex calc-num-simplify-mode
The @kbd{m N} (@code{calc-num-simplify-mode}) command turns off simplification
$$ a_{i+1} = { a_i + b_i \over 2 } , \qquad b_{i+1} = \sqrt{a_i b_i} $$

-@c @cindex Root-mean-square
-@c Another commonly used mean, the RMS (root-mean-square), can be computed
-@c for a vector of numbers simply by using the @kbd{A} command.
+@kindex u R
+@cindex Root-mean-square
+@tindex rms
+The @kbd{u R} (@code{calc-vector-rms}) [@code{rms}]
+command computes the RMS (root-mean-square) of the data values.
+As its name suggests, this is the square root of the mean of the
+squares of the data values.

@pindex calc-vector-sdev
replace any hyperbolic functions in the formula with the appropriate
combinations of @samp{sinh}s and @samp{cosh}s before simplifying.

The definitions of many units have changed over the years. For example,
the meter was originally defined in 1791 as one ten-millionth of the
-distance from the equator to the north pole. In order to be more
+distance from the Equator to the North Pole. In order to be more
precise, the definition was adjusted several times, and now a meter is
defined as the distance that light will travel in a vacuum in
1/299792458 of a second; consequently, the speed of light in a
The unit of volume ``liters'' can be referred to by either the lower-case
@code{l} or the upper-case @code{L}.
-The unit @code{A} stands for Amperes; the name @code{Ang} is used

+The unit @code{A} stands for amperes; the name @code{Ang} is used
+for angstroms.
The unit @code{pt} stands for pints; the name @code{point} stands for
a typographical point, defined by @samp{72 point = 1 in}. This is
the unit names for pint and parsec will simply be @samp{pint} and
@samp{parsec} instead of @samp{pt} and @samp{pc}.

The unit @code{e} stands for the elementary (electron) unit of charge;
because algebra command could mistake this for the special constant
@expr{e}, Calc provides the alternate unit name @code{ech} which is
example, @code{500 Hz} gets converted to
@code{B_4 + 21.3094853649 cents} and @code{84} to @code{C_6}.

+The @kbd{C-y} command can be given a prefix, which will interpret the
+text being yanked with a different radix. If the text being yanked can be
+interpreted as a binary, octal, hexadecimal, or decimal number, then a
+prefix of @kbd{2}, @kbd{8}, @kbd{6} or @kbd{0} will have Calc
+interpret the yanked text as a number in the appropriate base. For example,
+if @samp{111} has just been killed and is yanked into Calc with a command
+of @kbd{C-2 C-y}, then the number @samp{7} will be put on the stack.
+If you use the plain prefix @kbd{C-u}, then you will be prompted for a
+base to use, which can be any integer from 2 to 36. If Calc doesn't
+allow the text being yanked to be read in a different base (such as if
+the text is an algebraic expression), then the prefix will have no
+effect.
