square.call(2) # => 4 power.call(2, 4) # => 16
Erlang:
-module(power). -compile(export_all). sqaure(X) -> X * X. pow(X, 0) -> 1; pow(X, Y) -> X * pow(X, Y-1). geometric_pow(_, 0, Acc) -> Acc; % It’s interesting that if 1 and 2 aren’t “unrolled”, % the linear implementation beats geometric_pow. ...

Aspect-oriented programming and security →
