[erlang-questions] Binaries

[Sverker Eriksson]

If you mean 16#1450000001, then

<<16#1450000001:40/big>>

will give you a 5 byte (40 bits) big endian format

<<16#14,16#50,16#00,16#00,16#01>>


If you mean 1450000001 as a decimal integer, then my guess is you do not
actually want that.


integer_to_list produces ASCII characters.
