I don't understand this observation.  What number of decimal digits did you
request?  There are 18 decimals in the first number, which seems like a
lot, unless you explicitly requested that?

If you are using the default output precision, then the second number makes
it look like the code is outputting "full FP precision", as opposed to the
stated 15 as per the manual.  This is reasonable and desirable IMO.
