but as Prof Ripley has said much earlier in this thread :
Why don't you use the C version from R's source? R is Open Source !!
R's version (of the *four* most common Bessel functions) stems
from the Netlib "Specfun" collection,
was ported to C by me and has been slightly fixed more than once
AFAIR.
