Table of Contents

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:

Step by Step solution about How to resolve the algorithm Averages/Root mean square step by step in the Sather programming language

Source code in the sather programming language

class MAIN is
  -- irrms stands for Integer Ranged RMS
  irrms(i, f:INT):FLT
    pre i <= f
  is
    sum ::= 0;
    loop
      sum := sum + i.upto!(f).pow(2);
    end;
    return (sum.flt / (f-i+1).flt).sqrt;
  end;

  main is
    #OUT + irrms(1, 10) + "\n";
  end; 
end;
