Replying to [comment:35 catalyst]:
> Also intermediate results with greater precision may occur (e.g., on x87
-- this is probably how you got greater than 53 bits of precision reported
in your tests with the "naive" approach) and maybe we should allow those?
Unless teor's system or compiler is outdated garbage it will use the SSE2
unit for floating point math.
