About this app

The result is the percentage increase, with three decimal places and rounding. Of course, the calculation of the decline is also supported.
For example, with three decimal places, 10.1457% is rounded to 10.146%.
When displaying the result, add the original value and the present value to avoid confusion with the previous calculation.

Increase calculation formula
Taking stock prices as an example, how are the stock price declines and rises calculated?
For example, if the closing price of a stock was 100 yesterday and the closing price today is 110, then the corresponding increase calculation formula is (110-100)/100=10%.
