Heaviside step function

The Heaviside step function can be defined as

\[\begin{split}H(x) = \begin{cases} 0, &x < 0, \\ 1, &x \ge 0. \end{cases}\end{split}\]

Write a function that implements the Heaviside step function following the given definition:

heaviside_step_function(n)

Return the value of the Heaviside step function of n.

Parameters:n (float) – The number of which the Heaviside step function should be computed. Returns:The value of the Heaviside step function of n. Return type:int
