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 check_type_forward(self, in_types):
      type_check._argname(in_types, ("x",))
      x_type = in_types[0]
      type_check.expect(x_type.dtype.kind == "f")

label_desc: Use image node_id 2 for calling the ClippedReLU obj's underlying member method code with example usage: obj.check_type_forward(in_types) without return types
