T. Gomes" The functions in the nexttoward family are special, in the sense that they always have a long double argument, regardless of their suffix (i.e.: nexttowardf and nexttoward have a long double argument, besides the float and double arguments). On top of that, they are also special because nexttoward functions are not part of the _FloatN API, hence __nexttowardf128 do not exist. This patch adds 4 new function implementations for the new long double format: __nexttoward_to_ieee128 __nexttowardf_to_ieee128 __nexttowardieee128 (as an alias to __nextafterieee128) 2018-06-19 Gabriel F.
