--- Comment #2 from newbie-02 <newbie-02 at gmx dot de> --- (In reply to Joseph S. Myers from comment #1) hello and thank you very much!!, > The decimal rounding mode is set with fe_dec_setround. found in my directories that I already had experimented with that, a distinct include of libdfp/dfp/fenv.h made progress, but also with `fe_dec_setround(FE_DEC_TONEARESTFROMZERO)`, successful as `if ((r = fe_dec_getround()) == -1)` produces '4', the implicit rounding for the addition stays with 'to even'. :-( will continue research tomorrow. the strategic discussion is above my experience, from POV wanting an alternative for people fed up with bin-FP imprecision it would be: - good if it works, - is easy to find, - wouldn't require much 'info gathering' and configuration effort,
