(operator-): Don't apply 'neg' to a nan. (neg): Return src if it is a qnan. 2005-05-20 Dave Brolley <brolley@redhat.com> * fp.cxx (pack_any): Ensure that nan results have a positive sign. (operator-): Simply call operator+ with the rhs negated. * fp.h (is_negative): New method of fp. 2005-05-13 Dave Brolley <brolley@redhat.com> * fp.h (fp): All arithmetic operator methods are now members of class fp. * fp.cxx (fp): Likewise. 2005-04-27 Dave Brolley <brolley@redhat.com> * fp.cxx (fp::unpack): Only perform sanity check for non-nans. 2005-04-12 Dave Brolley <brolley@redhat.com> * fp.h: Move static constants and functions to top of file for visibility within the file.
