I have to clarify another step from my previous question @ log ratio in gene expression array

If two values are A-32 B -18 If I have to present data as FC and log FC For FC it will be 32-18= 1.7 this will be a linear FC

and log FC= LogA-logB will be 5-4.1=1.19= 0.2 when we use log values of A and B, Do we again shift the results to log value- log 1.19

Or we present logFC as log of linear FC- meaning log (1.7)= 0.8 What is the best and correct way of presentation.
