What is this


class some_kind_of_simple_filter
{
  public:

    some_kind_of_simple_filter(float coefficient_) : coefficient(coefficient_), value(0.0f) {}

    void sample(float f)
    {
      value = coefficient * value + (1.0f - coefficient) * f;
    }

    float get()
    {
      return value;
    }

  protected:

    float coefficient;
    float value;
};

/prog/, what is this kind of filter called?  I've been using it forever, and it is really nice for smoothing out sampled data.  I've just never known what it's called.
