My understanding is that the simplifier gets invoked by calling WN_CreateExp[0123] instead of WN_CreateExp[0123].

I think there is a way to include simplifier in fortran FE. My question is, are you using that? Or writing your own? If you are writing your own, I just want to point out the potential problems in terms of rounding/...
