I like the idea, but on a second thought, it is easily fooled:

    >>> 3.0/10.0 == 1.0/10.0 + 2.0/10.0
    False

No need to even go up to this point. Numbers that are too different are enough 1e300 + 1 will be equal to 1e300. And it would still be even if 1 was added 1e300 times.

And you could not write 1e300 since it is not exact

You need to write 1000000000000000052504760255204420248704468581108159154915854115511802457988908195786371375080447864043704443832883878176942523235360430575644792184786706982848387200926575803737830233794788090059368953234970799945081119038967640880074652742780142494579258788820056842838115669472196386865459400540160

Now, I feel dumb for not noticing the "+ 1" was not needed. Completely forgot 1e300 would not map on a factor of 2, thanks for the correction.
