* @param {Date|Number} date - the date to be changed
* @param {Number} amount - the amount of hours to be added. Positive decimals will be rounded using `Math.floor`, decimals less than zero will be rounded using `Math.ceil`.
* @returns {Date} the new date with the hours added
* @throws {TypeError} 2 arguments required
*
* @example
* // Add 2 hours to 10 July 2014 23:00:00:
* const result = addHours(new Date(2014, 6, 10, 23, 0), 2)
* //=> Fri Jul 11 2014 01:00:00
