Problem Statement
Compute the Root mean square of the numbers 1..10.
The root mean square is also known by its initials RMS (or rms), and as the quadratic mean. The RMS is calculated as the mean of the squares of the numbers, square-rooted:
Let's start with the solution:

Source code in the standard programming language
fun rms(v: real vector) =
let
val v' = Vector.map (fn x => x*x) v
val sum = Vector.foldl op+ 0.0 v'
in
Math.sqrt( sum/real(Vector.length(v')) )
end;
rms(Vector.tabulate(10, fn n => real(n+1)));
