Michele,
So I think the patch you had plus tests
testsuite/tr1/5_numerical_facilities/special_functions/09_cyl_bessel_j/check_value.cc
testsuite/tr1/5_numerical_facilities/special_functions/11_cyl_neumann/check_value.cc
plus I'd like the new tests also in
testsuite/special_functions/08_cyl_bessel_j/check_value.cc
testsuite/special_functions/10_cyl_neumann/check_value.cc
for C++17.
Put that up with a Changelog and see if we're all good.
Thank you for going through this and other math issues.
Ed
