2037	Math expressions flattened incorrectly	Bill Janssen	probably noone	"The flattening code seems to be dropping terms from mathematical expressions.  If you take the model



{{{
model showBug

  encapsulated type OperatingModes = enumeration(M1, M2);
  parameter OperatingModes mode = OperatingModes.M1;
  parameter Real mode_amount = 1.0;

  parameter Real d = (if mode == OperatingModes.M2 then (10 + (1.0 - mode_amount) * 1.0e60) else Modelica.Constants.inf);

end showBug;
}}}

and flatten it with ""omc"", you get this:


{{{
% omc showBug.mo ModelicaServices Modelica
class showBug
  parameter Real mode_amount = 1.0;
  parameter Real d = if mode == showBug.OperatingModes.M2 then 1e+60 + -1e+60 * mode_amount else 1e+60;
  parameter enumeration(M1, M2) mode = showBug.OperatingModes.M1;
end showBug;
%
}}}

You see that the expression for ""d"" is incorrect."	discussion	closed	high	1.12.0	Frontend	trunk	worksforme
