Digit of fuel entries about pypact HOT 1 CLOSED

Yes - good spot!

If I remember correctly, FISPACT-II takes a maximum of 13 or 14 decimal places, otherwise you get this not so useful error message, so indeed this needs to be taken into account.

This code is a bit old now and we would be better off using f-strings now anyway. I would just vote to always dump to 10 decimal places anyway, since this is plenty of accuracy and most of them are just noise.

Something like:

     def __str__(self):
         strrep = f"FUEL {len(self.entries)}"
         for i in self.entries:
             strrep += f"\n{i[0]} {i[1]:.10E}")

By all means do a pull request and we can fix this.
