object_hexid incorrect

T. Onoma

12/1/2004 2:49:00 PM

Can anyone help me understand why these are not the same, and how to fix?

class Object
def object_hexid
return "0x#{'%x'%(self.__id__)}"
end
end

o.inspect
=> "#<Object:0x40335764>"

o.object_hexid
=> "0x2019abb2"

Thanks,
T.

uln% ruby -e 'p "%x" % (2*0x2019abb2)'
"40335764"
uln%

Did you notice that (0x40335764 >> 1) == 0x2019abb2 ?
