A more accurate answer should never cause your algorithm to
fail. It's like putting better parts in your car causing the
car to fail.
This is all quite discouraging from a scientific programmers
point of view. Precision is important, more precision is good,
but reproducibility and predictability are critical.
Tables of constants that change value if I put a `static` in
front of them?
Floating point code that produces different results after a
compiler upgrade / with different non-fp-related switches?
Ewwwww.
