 * Example: limit the output of this computation to between 0 and 255
 * <pre>
 * (x * 255).clamp(0, 255)
 * </pre>
 *
 * @param {Number} min The lower boundary of the output range
 * @param {Number} max The upper boundary of the output range
 * @returns A number in the range [min, max]
 * @type Number
