why so different

nderstand the Num actually have the traditional behavior which leads this: 0.1.Num() + 0.2.Num() != 0.3.Num() And Rat is awesome cos deal nice to the real world. Anyway, I do not expect so different results between Rat and Num. Thanks, Aureliano Guedes -- Aureliano Guedes skype: aureliano.guede
