Managing foreign currencies in a business application

Question

friend, do you know how to Manage foreign currencies since the currencies values are changing day by day

Answer 1

Financial currencies are a case of time series data. Every computational language has its own way to deal with them. For instance, to smooth out the display of a series you can specify a roll period. This will result in each plotted point representing an average (a moving average) of the number of timestamps specified in the roll period.
You should be more precise in order to get better support.
