Erm, the numeric is doing integer ops too mostly, no? Perhaps I'm missing something here.. What *exactly* makes it faster than numeric, and why couldn't numeric use that improvement? The one thing I can think of right off would be having a 64bit-base numeric type instead of the current 32bit-base (which limits us to base-10,000 while 64bit would give us base-1,000,000,000, which means more done in one operation and so less work overall- *if* you can do fast 64bit integer operations, which isn't necessairly the case on all architectures...). If that's where the improvment is then let's add a 'numeric64' type. Thanks, Stephen
