Thanks, but what we're looking for is is what format the data is in in  
register. For example, in 32-bit C, bytes/shorts are computed as ints and  
truncated back down. I've found some references to 64-bit native integers  
in the CLI spec, but nothing definative.

The question boils down to is b == 0 or not:

int a = 2147483647;
long b = a+a+2; // or long long depending on platform
