Well, I think I will use the e20 format. to have the greatest possible precision, also because this rounding creates problems for the subsequent derivative calculations, so to have the smallest gap I have to be as precise as possible.   Thank you so much for your perfect answer! Sara ... View more

Hi! I have a problem with a decimal variable that is the result of an arithmetic operation. Suppose this:   data dataout; format var_c commax20.16; var_a = 556.52; var_b = 617.78000; var_c = var_a / var_b - 1; run; The value of var_c in the output dataset is -0,0991615138075000, but it should actually be -0,0991615138075043 How can I make sure that the precision reaches the 16th decimal?   Thank to all.
