Bug ID: 91156 Summary: The associated laguerre polynomial should allow nedative arguments. Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: emsr at gcc dot gnu.org Target Milestone: --- The associated Laguerre polynomial should allow negative arguments. It's not often used for negative arguments but it's a polynomial and it doesn't do anything nasty for negative arguments. Unlike the case for associated Lagendre polynomial the origin is not a branch point.
