Your details are off. 1.0 is precisely representable in double precision floating point with no error.

  Sorry, picked the wrong number. But I think the general idea is correct.

    I am pretty sure you were thinking of 0.1 which, indeed, requires an infinite number of digits to be represented in binary (like 1/3 in decimal).

      Probably. I just remember that this tripped me up big time a long time ago.
