Hi Lester, I didn't add restrictions specific to number representation in the draft ruleset yet, becausen while I think that's an important point, I didn't have time to study it in depth.
I know you're an expert on this as you continuously (rightly) raised the point. So, can you elaborate on this and send me or, better, publish on the list the detailed set of changes you suggest, including 32 bit vs 64 bit concerns if they fit. Today, conversion restrictions are rather limited as floats which don't fit in int give 0, and int to float is considered as always possible. I mean that must be technically incorrect, while unnoticed in the vast majority of cases. So can you write a consistent set of changes you would introduce ?
