State the example of pre- and post-conditions

Suppose that function f(x) should have a non-zero argument and return a positive value. We can document these pre- and post-conditions in comments and incorporate a check of the precondition in this function's definition, as demonstrated below

# Explanation of what f(x) computes

# @pre: x != 0

# @post: @result > 0

def f(x)

  raise ArgumentError if x == 0

  ...
