#6171: nonconforming behavior of inverse functions on branch cuts
----------------------------------------------------+-----------------------
Reporter: Richard B. Kreckel <kreckel@â¦> | Owner: johnmaddock
Type: Bugs | Status: closed
Milestone: To Be Determined | Component: math
Version: Boost 1.48.0 | Severity: Problem
Resolution: fixed | Keywords:
----------------------------------------------------+-----------------------
Changes (by johnmaddock):
* status: new => closed
* resolution: => fixed
Comment:
(In [75933]) Fix complex number routines to work with signed zeros,
changes involve:
* Use boost::math::signbit rather than comparison to zero.
* Use boost::math::changesign rather than unary negation (unary negation
fails for Intel on Linux when the argument is a zero).
* Update to use boost::math::isnan/isinf rather than the old code.
* Update to use boost::math constants.
Fixes #6171.
