Relational operators give inconsistent results

[raph85@…]

In the following model, relational operators give inconsistent results when the compared variable is set using an "if-expression":
model Test

Real y;
Boolean b1 = y < 100.0;
Boolean b2 = y <= 100.0;
Boolean b3 = y == 100.0;
Boolean b4 = y >= 100.0;
Boolean b5 = y > 100.0;

equation

y = if time > 2 then 100 else 0;

end Test;

The results show that b1 b2 and b3 are all true at the same time, which is illogical.
