Quote: Hi,
I'm just trying to help to get the documentation improved for future users; I will report anything that I find.
As in another topic, there are some things that can be hyperlinked liked the references to man(x) pages, like "erlang(3)".
I've noticed in the html docs: /doc/reference_manual/data_types.html
Some of the examples that are given don't give the same output on my Erlang R11B via the Erlang emulator/shell v 5.5.4, for example,
Quote: 5> list_to_binary("hello").
<<104,101,108,108,111>>
Instead I get Quote: 56> list_to_binary("hello").
<<"hello">>
What's the correct behaviour? Or is the output of an array of integers just automatically being converted to a string by the "print"ing to the console/shell?
I tried this on a windows xp machine.
<<104,101,108,108,111>> and <<"hello">> are the same, as the string datatype does not exist. It is represented as a list of ascii by the VM. The output, I would guess, is not defined between releases.
With strings, the shell will notice if a list consists of ascii and print it out as a string. That is obviously not the case with binaries. |
