@RudiC, when experimenting I could not get that to work aerlier using +0. Your approach of a small number seems to work.
I found though that if the value is too small then it does not work again, i.e. 1E-12 works, but 1E-13 does not. So One would need to choose carefully, so perhaps it is better not to rely on this..
