Why does [9] return as "\ t" in Erlang?

Question

I work on some Erlang tutorials and notice when I enter

[8].

VM returns "\ b" or if I type

[9].

VM returns "\ t"

I am confused why this is happening. Other numbers are returned as a list of this number:

[3].

returns as [3]

[4].

returns as [4] etc.

I think the question is why erlang VM returns it this way? Perhaps an explanation of the list [65] and the list? "A".
Another related element is also confused: Type conversion, conversion of a list to an integer is performed as follows:

list_to_integer("3").

Not

list_to_integer([3]).

What error returns

Kadaj answered your first question. As for the second question list_to_integer, if you look at the documentation , the majority of list_to_XXXfunctions, in addition to binary, bitstringand tupleview them as a string argument. Calling them string_to_XXXmay be clearer, but changing the name will break a lot of code.
