[erlang-questions] Newbie Question about io:format
Tue Feb 21 10:15:56 CET 2017
First, thank you because this is a great resource.
Second, I started writing basic programs every day to improve my Erlang
coding. I wrote a simple program that calculates the average of a list of
numbers. But I keep getting this error about io:format.
io:format("List is empty ~n");
%% determine number of items in the list to calculate average%%
prices(L) when is_list(L) ->
Size = length(L),
Sum1 = lists:sum(L),
Av1 = Sum1 / Size,
io:format("The average equals ~n", Av1).
Eshell V8.2 (abort with ^G)
1> L = [1,2,2,2,3,3,4].
** exception error: bad argument
in function io:format/3
called as io:format(<0.50.0>,"The average equals
Why am I getting '**exception error:'?
Thank you, I hope this isn't too newbie a question.
