Yes it does - everying is serialized as text - see the rational for
this with the documentation.
floats and doubles are rendered in the maximum precision the the C++
implementation permits. If the archive read by an implementation
that supports lower precision - data will be lost. This is not
addressable from this library.
In general there is no guarentee that floating/doulble values will be
exactly ported from environment to environment. Indeed it is
impossible to implement such a guarentee.
On the same environment - no precision should be lost.
