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.
