+1. If you aren't trying to get the format exactly so, it's not clear
why you're bothering with to_char() at all.

Five (or more?) E's seems like a natural extension to me. However, that
still leaves us with the question of what to do when the exponent
doesn't fit in however many digits we'd like to print. Seems like the
options are* print #'s* force the output wider* throw an error
None of these are very nice, but the first two could cause problems that
you don't find out until it's too late to fix. What about throwing an
error?
Sorry if this was already covered in the thread, but: anybody know what
Oracle does for this?
