class_docstr: Clipped Rectifier Unit function.
  
  Clipped ReLU is written as
  :math:`ClippedReLU(x, z) = \min(\max(0, x), z)`,
  where :math:`z(>0)` is a parameter to cap return value of ReLU.
code: def forward_cpu(self, inputs):
      self.retain_inputs((0,))
      (x,) = inputs
      return (
          utils.force_array(
              numpy.minimum(numpy.maximum(0, x), self.cap), x.dtype
          ),
      )
