Function that returns the price of an American Digital Call
Description
Digital options, also called binary option, are options which pay a fixed payoff when the underlying stock price crosses the strike price. Thus, American Digital Options are automatically exercised as soon as they get in the money. In addition, American Digital options can be splitted in two categories: cash-or-nothing (which pays a fixed payoff in case of the underlying stock price ends up in the money) and asset-or-nothing (which pays the value of the underlying stock in case of the underlying stock price ends up in the money) options.
