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. Vlad
