Hi, just a guess but the number format looks like a different locale
(from mine at least).  I tried your example under a couple different
locales on my system but I still don't see these error messages.

Three things to check:

1. What is your locale configuration?

2. If you set LC_ALL=C in your environment do the errors go away?

3. If you run octave with --norc do the errors go away?
