I read from documentation: 
You can also store data in network order to allow
easy sharing across multiple platforms, or when storing
on a socket known to be remotely connected. The routines
to call have an initial n prefix for network, as in nstore
and nstore_fd . At retrieval time, your data will be
correctly restored so you don't have to know whether you're
restoring from native or network ordered data. Double
values are stored stringified to ensure portability as
well, at the slight risk of loosing some precision in the
last decimals.

This version of Storable will defer croaking until it encounters a dat
+a type in the file that it does not recognize. This means that it wil
+l continue to read files generated by newer Storable modules which ar
+e careful in what they write out, making it easier to upgrade Storabl
+e modules in a mixed environment.
