-module(temp).
-export([convert/1]).
convert({c, Temperature}) ->
{f, c2f(Temperature)};
convert({f, Temperature}) ->
{c, f2c(Temperature)};
convert(Other) ->
{invalid_object, Other}.
c2f(X) ->
((9/5) * X) + 32.
f2c(X) ->
(5/9) * (X - 32).
-module(mathStuff).
-export([perimeter/1]).
perimeter({square, Side}) ->
4 * Side;
perimeter({circle, Radius}) ->
2 * 3.14 * Radius;
perimeter({triangle, A, B, C}) ->
A + B + C;
perimeter(Other) ->
{invalid_object, Other}.
