Almost... there are a few (rare) cases where 18 Digits are needed! But 18
is indeed the 'right' number, assuming the system does proper IEEE rounding.
I am not an expert on this, but I used to have one as an employee (back when
I was manager of the Mathematics Group at Maple), and I learned this from
him.

Correctness and ease-of-use do clash badly when it comes to FP. I prefer
correctness, because latter syntactic sugar can deal with the ease-of-use
problem, but the other way around does not work at all.
