Thanks for the feedback everyone. FFI looks very interesting.
does Erlang make guarantees about storing data in contiguous memory?
My guess is that the binary data type was designed with that in mind.
However, do I understand correctly that floats cannot be stored in a
binary data type?
Eshell V5.6.3 (abort with ^G)
1> X = <<1,3,9>>.
2> Y = <<1.0,3.0,9.0>>.
** exception error: bad argument
or am I missing something obvious?
Can anyone refer me to the source file that defines binary data types?
