In short, Calc = maintains a 'word size' and clips all results of binary operations to = that size. Apparently, Calc clips the argument for good measure before = even performing the right-shift. The default word size is 32 bits; you = can change it using "b w". Whether this is the best design can be debated, of course. Tell us if = you are happy with this explanation, or if you think it should work in a = different way. (Can't promise any major changes, though.) A very modest reform would be to set the default word size to 64 bits, = to keep up with the times.
