probably you should avoid extra precision and all the
issues it brings, as well as speed up your program, by
using SSE 64-bit arithmetic (using the appropriate gcc
flags)
Indeed. -mpc64 fixes the issue and proper 53-bit rounding is applied.
Thanks a lot.
If you are going to set 64-bit mode, you might as well specify
SSE artihmetic, it will be significantly faster for most applications.
