This problem has been around about as long as computers I think. I used
to have an old pascal routine that would tell you what format code you
needed for a given number, assuming you wanted to see the whole number,
but not anymore more than is necessary (for instance, 8.6). Has anyone
written such a function for IDL?

You could probably piece together what you need using this function I just
found on the IDL Libraries Browser at Washington (see below).

Good luck,
Chris
