Yes, it does.I did not jnow that 9007199254740992 is a power of 2. It
looks that it is a way that the developpers used.

However, I would not agree that one can say that it is an infinite
precision of 0.14  in usual sens. In fact the error introduced by the
transformation is about MachinePrecision.
