Do sns files containg 32 bit FP data?

[raveling]

I was just wondering whether .sns file retain the complete data loader from all the brackets or and hdr source file? Are sns file 32 bit floating point? Finally am I losing anything when i save into sns files? I want to know where in my workflow I should use SNS HDR to keep as much data as possible for as much of the workflow as possible.

Thanks,
Tim
