I'm very respectful when I see a number with so many digits in a row. :-)
I'm not sure that this will be of any interest to you, number crunchers,
but a research team in computer arithmetics here reported some major
results lately: they claim that they "solved" the Table Maker's Dilemma
for most common functions in IEEE-754 double precision arithmetic.
(and no, don't ask me what this means ;-) For more information, see:
