      :param dict params: A dict containing API call parameters.
  
      :param str name: The name of the parameter to set.
  
      :param float value:
          The value of the parameter. If ``None``, the field will not be set. If
          an instance of a numeric type or a string that can be turned into a
          ``float``, the relevant field will be set. Any other value will raise a
          `ValueError`.
  
      :param float min:
          If provided, values less than this will raise ``ValueError``.
  
      :param float max:
          If provided, values greater than this will raise ``ValueError``.
  
      :returns: ``None``
