Bug #: 56216
Summary: TR1 bessel functions bomb at x == 0!
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: 3dw4rd@verizon.net
The Bessel functions
std::tr1::cyl_bessel_i(double nu, double x)
std::tr1::cyl_bessel_j(double nu, double x)
return -nan at x=0 instead of 0 (nu==0) or 1 (nu > 0).
I have a patch that fixes this and some other things.
