Add Stock Quantity Calculator 1.21

This calculator simply calculates how many additional shares you need to buy to match a certain average unit price of your stock.

This calculator inputs the average unit price of stocks, the number of stocks held, the current price of stocks, and the desired average unit price, and shows the number of additional purchases to the user.

*** If the calculation amount goes beyond about 922 ten-million billion, the result will not be reflected correctly because the device can not be calculated. In general, however, you will not go beyond this range unless you enter the wrong number.
