Hi, I have a seemingly easy question that has been keeping be busy for quite a while. The problem is the following: 0.1 + 0.1 + 0.1 == 0.3 [1] FALSE Why is this false? Another example is 0.2 + 0.1 == 0.3 [1] FALSE or 0.25 + 0.05 == 0.20 + 0.10 [1] FALSE However, I do get TRUE if I use integers, or for example the following 0.1 + 0.1 == 0.2 [1] TRUE It is probably something very basic, but I did not manage to find the answer. Thanks, Michael
