support:
2005-06-14 Dave Brolley <brolley@redhat.com>
* fp.h (do_round,do_normal_round,do_normal_underflow,do_normal_overflow)
:
Now virtual.
* fp.cxx (do_normal_overflow): Round up to infinity only if
the result is positive.
(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.
(get_status): New method of fp.
(get_class): Likewise.
(qnan_fraction): Likewise.
(snan_fraction): Likewise.
(qnan_exponent): Likewise.
(snan_exponent): Likewise.
* fp.cxx (fp_to_int): throw fp::overflow for overflow.
(pack_any): Use [sq]nan_{exponent,fraction} to construct nans.
(unpack): Initialize status to 'ok'. Set class and status using
is_qnan_fraction and is_qnan respectively.
2005-03-18 Dave Brolley <brolley@redhat.com>
* fp.cxx: Move static items from here.
* fp.h: To here. Make some methods virtual. Make private members
protected.
(is_inexact): New method.
