-module(tut).
-export([double/1]).
double(X) ->
2 * X.
saved that in tut.erl, placed it in the bin/ and tried to run it but it asks for a specific program to run.
Erlang (BEAM) emulator version 5.6.2 [async-threads:0]
Eshell V5.6.2 (abort with ^G)
1> c(tut).
../tut.erl:none: no such file or directory
error
2>
so which install do i need?
how do i define a function?
can i do that directlyin the shell?
like in python:
def sq(x): return x*x
how would i dot hat in erlang?
