[h5 Floating-point format]
If you wish to find details of the floating-point format for any particular processor,
there is a program
[@../../../example/inspect_fp.cpp inspect_fp.cpp]
by Johan Rade which can be used to print out the processor type,
endianness, and detailed bit layout of a selection of floating-point values,
including infinity and NaNs.
