> Is a BEAM file big-endian or little-endian?
Numeric literals in Beam files are stored in big-endian order.
In the process of loading Beam files, among a lot of other code
rewriting, numeric literals are converted to the native endian of
the CPU the Erlang machine is runing on. Integer literals that will
not fit in a machine word are converted to a big number format.
On a 32 bit CPU, signed integers up to 28 bits can fit in a word
(the remaining 4 bits are used for the type tag).
