For reference for anyone working on improving accuracy for Bessel
functions (an issue for all the versions for all floating-point formats,
not just x86 / x86_64): http://www.cl.cam.ac.uk/~jrh13/papers/bessel.ps.gz
discusses how to achieve correct rounding for Bessel functions of any
fixed constant order (jn/yn will be harder).
