You, as the user of the number, have to specify something about what you want for the
output format. E.g. maximum length, how many decimal places, etc. IDL, and computers in
general, have absolutely no intelligence - that's where the user comes in. :o) If you
don't know what the size of the number will be, use exponential format.

You haven't defined what "right" is in a way a program can understand it.
