Dear All,
I have a seemingly very simple question, but I just cannot figure out the answer. I attempted to run the following:a=0.1*(1:9);which(a==0.3);it returns integer(0). But obviously, the third element of a is equal to 0.3. 
I must have missed something. Can someone kindly explain why? Thanks a lot.
Regards,Dajiang
