Hi all, my problem is that R does wrong calculations, when the result should be zero. I have the following code: RD_Var1 <- ((0.1*(1-0.1))/100)+((0.2*(1-0.2))/100) RD_Var2 <- ((0.1*(1-0.1))/100)+((0.2*(1-0.2))/100) RD_1 <- 0.1-0.2 RD_1 RD_2 <- 0.1-0.2 FEM_Eff_RD <- ((1/RD_Var1)*RD_1+(1/RD_Var2)*RD_2)/(1/RD_Var1+1/RD_Var2) Q_RD <-
