Hi
I have some problems with parentheses/brackets in some of my equations. This just a simple exampel and I hope the comments in the code will explain the problem.

model Testar
  constant Real A = 2;
  constant Real B = 3;
  constant Real C = 5;
  // I wish to whrite equation G as: G = 10 / ((A+B)/2) * C; which is equal to 20
  //
  Real G;
  Real H;
  Real I;
  //
equation
  // When I save the model, OpenModelica choose to read the equation as in equation G below, without parentheses outside (A+B)/2.
  G = 10 / (A + B) / 2 * C;     // G = 5
  //
  // If i split up equation G in I and H as follows below, I will get the correct answer, which is 20.
  I = (A + B) / 2;     // I = 2.5
  H = 10 / I * C;     // H = 20
  //
end Testar;

When it is just constants I am calculating I could do parts of the calculation outside the equation.
But, is there a way to solve equation G without split it up in several equations?
