greater than an integer is not an integer, even when reduced to a sufficently small number.

Well, this does get interesting. To continue with your example: a: 2000000001 b: 10000000005 / 5 type? a ;integer! type? b ;decimal! a = b ;true, as it should be same? a b ;true, as I guess it is strict-equal? a b ;false, ahhh, I feel better to-integer b ; 2000000001 type? b ;decimal!, wow, that is interesting to-decimal a ;2000000001 type? c ;integer! It is interesting that sometimes REBOL "leaves" it as it was (a decimal or an integer), despite trying to coerce it. I can't tell if this is a bug or a feature, but I could imagine circumstances where it might trip up programming logic. Thanks. --Scott Jones
