Not sure if this answers your question, but, in my opinion, it's somewhat of an irrelevant factor, in that if you are cutting it that close, you're probably not going to be satisfied with the end result. My experience has been that most of various materials in your home expand and contract at different rates, and, of course, rafter height varies from one to the next, so, as just one example, you do not want the top edge of your facia pressed tightly to the bottom of the drip edge. Your weather seal comes from layering the components in the correct order to permit water runoff, not from trying to maintain machine fits between the components. Likewise, you do not want to "over nail" these components in place, as they need to be able to expand and contract without pulling themselves loose.

Ditto on what Dexter said,
Normally you don't allow anything for the bend, as it is such a tiny amount, it doesn't need to be factored in.
