Agreed. Is there an IEEE name for this "round away from zero" mode?
I can't seem to find one. I guess that's how somebody got confused
and labeled it "roundTiesToAway".

Rounding mode                    IEEE name              'ROUNDMODE'
---------------------------------------------------------------------------
Round to nearest, ties to even   'roundTiesToEven'      '"N"' or '"n"'
Round toward positive infinity   'roundTowardPositive'  '"U"' or '"u"'
Round toward negative infinity   'roundTowardNegative'  '"D"' or '"d"'
Round toward zero                'roundTowardZero'      '"Z"' or '"z"'
Round away from zero                                    '"A"' or '"a"'

Possible patch attached.

Andy
