Re: [Boost-users] cross-platfrom binary serialization?

Most modern platforms use the IEEE 754 (1985) encoding for binary data
(float/double). But I suppose there is still the (easy to handle) endianess
issue. http://www.appinf.com/download/FPIssues.pdf

meanwhile I found the svn URL for boost, at 
http://svn.boost.org/svn/boost/trunk

I'm looking at the sample, and I see the following comment:

// "Portable" input binary archive.  It addresses integer size and 
endienness so
// that binary archives can be passed across systems. Note:floating 
point types
// not addressed here

so I guess floating point type support needs to be added to this 
implementation? what would be your suggestion to implement floating 
point support? use some portable binary representation for floating 
point types?
