Working with more than 16 digits?



Thanks for the clarifications!

That mystery seems to be documented:

,----
|  - Variable: FPPRINTPREC
|      default: [0] - The number of digits to print when printing a
|      bigfloat number, making it possible to compute with a large number
|      of digits of precision, but have the answer printed out with a
|      smaller number of digits.  If FPPRINTPREC is 0 (the default), or >=
|      FPPREC, then the value of FPPREC controls the number of digits used
|      for printing.  However, if FPPRINTPREC has a value between 2 and
|      FPPREC-1, then it controls the number of digits used.  (The minimal
|      number of digits used is 2, one to the left of the point and one to
|      the right.  The value 1 for FPPRINTPREC is illegal.)
