ECMA states that all arithmetic is done with double precision IEEE
floating-point, and the result of the calculation you use in your tests can not
be represented exactly. You could just write the full value of the result in
the tests or pick different calculations whose can be represented exactly. I'll
even do it while landing, if you want. For now, I'll r- the patch so no one
lands it.
