No, if the goal is to be portable with various platforms, you need to round to double by default, since single precision (almost no longer used for FP computations) and double precision are the only standard precisions in IEEE 754. -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / SPACES project at LORIA
