Yes, but those have nothing to do with normalization. I'm not quite sure why one would even mention them in this context. Fortran also has trig functions. > (I think normalization is too low level, isn't it?) Basically. It is related to details of the representation. The Fortran standard doesn't go into anything about representation details. -- Richard Maine | Good judgment comes from experience; email: last name at domain . net | experience comes from bad judgment. domain: summertriangle | -- Mark Twain

I apologyze, I didnt't try to bother anybody, I just thought about the relationship among data representation (being normalization one of the details), Fortran standards (being referred to in the question and answer), and portability. Sorry, Fernando. |
