     24 * Returns an object mapping supported casting modes to integer values for purposes of C inter-operation.
     25 *
     26 * ## Notes
     27 *
     28 * -   Downstream consumers of this mapping should **not** rely on specific integer values (e.g., `NO_CASTING == 0`). Instead, the object should be used in an opaque manner.
     29 * -   The main purpose of this function is JavaScript and C inter-operation of ndarray objects.
     30 *
     31 * @returns {Object} object mapping supported casting modes to integer values
     32 *
     33 * @example
     34 * var table = enumerated();
     35 * // returns <Object>
