  Booleans are rejected explicitly because ``bool`` is a subclass of ``int``
  in Python and would otherwise slip through numeric checks.

  Args:
      value: The value to validate.
      field_name: Field name used in the error message.
      minimum: Inclusive lower bound.
      maximum: Inclusive upper bound.
      allow_int: Whether integer values are acceptable.

  Returns:
      The validated value as a float.

  Raises:
      ConfigError: If the value is not a number or is out of range.
