playing around with erlang
I’ve been messing around with Erlang after picking up Erlang and OTP in Action(affiliate code) and hopefully I will be writing massively scalable applications soon because Erlang makes it so easy. Even though I’m not quite there, here is what I got so far:
-module(all_work).
-export([convert_temp/1]).
convert_temp({T,c}) ->
{T * 9/5 + 32,f};
convert_temp({T,f}) ->
{(T - 32)* 5/9,c}. A simple program to convert C to F.
24> c(all_work).
{ok,all_work}
25> all_work:convert_temp({73,f}).
{22.77777777777778,c}
26> all_work:convert_temp(all_work:convert_temp({73,f})). What is Next? Who knows.
