Probably because talking about the gory details would completely derail the
conversation, as I did.  :P  My apologies.

I think it's fine to do it when you're learning the language.  Just be
aware of it, and you should be ok.

Related: I saw a picture the other day on Google+ of an mailing envelope
whose zip code was written in scientific notation.  By computer, of course.
 Wish I could find it again...  Knowing the appropriate representations for
data is something you'll pick up as you learn a programming language.


Good luck!
