   * Compute the cube of a value, `x * x * x`.
   * To avoid confusion with `pow(M,3)`, this function does not apply to matrices.
   * If you wish to cube every entry of a matrix, see the examples.
   *
   * Syntax:
   *
   *    math.cube(x)
   *
   * Examples:
   *
   *    math.cube(2)            // returns number 8
   *    math.pow(2, 3)          // returns number 8
   *    math.cube(4)            // returns number 64
   *    4 * 4 * 4               // returns number 64
   *
   *    math.map([1, 2, 3, 4], math.cube) // returns Array [1, 8, 27, 64]
   *
   * See also:
   *
   *    multiply, square, pow, cbrt
   *
   * @param  {number | BigNumber | Fraction | Complex | Unit} x  Number for which to calculate the cube
   * @return {number | BigNumber | Fraction | Complex | Unit} Cube of x
