How do you do modulo or remainder in Erlang?

Question

I\'m brand new to Erlang. How do you do modulo (get the remainder of a division)? It\'s % in most C-like languages, but that designates a comment in Erlang.

Answer 1

mod(A, B) when A > 0 -> A rem B;
mod(A, B) when A < 0 -> mod(A+B, B); 
mod(0, _) -> 0.

% console:
3> my:mod(-13, 5).
