Subject: [PATCH 04/11] Addressed only a few issue from reviewer's comment.
Updated the RN and added a warning to tell the user about the presence of
nnan and ninf with full implementation. Changed the behavior of
multplication: when full implementation is required in the presence of nnan
and ninf it will implement basic implementation instead.
