You'll find that I'm a physicist, too. I have no formal CS training other than reading books and the Fortran standard. It does not matter if you consider the minus a part of the number. It is a unary minus operation according to the Fortran Standard, and that is how gfortran implements its behavior. You are relying on nonportable processor dependent behavior. I've told you how to make your code portable. It is up to you to use the advice or ignore it.
