[Some day hopefully I'll remember to change the to: address to python-list@python.org
instead of the original sender. I always end up sending the first reply to the
sender, then going "oops, forgot to hit 'reply-all'", and sending another copy to the
list.]

It displays '3E+1' instead of '30.0'.
As I can't reproduce I'm looking for an idea brainstorm of what
could be causing this. What would be choosing to display such a
normal number in scientific notation?
As I understand it, the Python string formatting operations
<URL:http://docs.python.org/library/stdtypes.html#string-formatting>
use the operating system's C library to perform (some of?) the
formatting.
The different behaviours you see might therefore be caused by
different C libraries in the operating system.
To avoid these and related problems, I would avoid floating point
wherever possible and use the ‘Decimal’ type for representing decimal
numbers.
Thanks. I forgot to mention that all numbers are already instances of
decimal.Decimal, not float. As I mentioned in a prior message, they do go
through a
locale.format() call to display the value.
